Due to problems with the windows installer 5 I must rename msi.dll for reinstallation. That's not possible in save mode/as administrator (access denied). Of course the service is stopped. Any hints?
Edit: My problem is that I can't install msi files anymore. Everytime after some dialogs I get an error message that the corresponding msi file can't be read. I have tried any infos I found in the www universe and lost a lot of time already. E. g. I replaced the registry settings, used sfc /scannow without success.
In Windows 7 there is no dllcache, so I really don't know what is preventing renaming.

This sounds a little bit strange. If you see MSI dialogs and the install fails when you kick it off there must be something else wrong. I assume you have, but have you verified that the problem exists with multiple MSI files? Try with a fresh MSI file, preferably one that you downloaded fresh from the Internet. Try to run from the local disk and from a network disk.
Have you enabled logging for the install? Try to do so with flush to log enabled (the ! character enables continuous flushing to log so that an msiexec.exe crash doesn't leave an empty log file):
msiexec.exe /i C:\Path\Your.msi /L*vx! C:\Your.log
See msifaq.com for more details (logging faq entry). Search for "value 3" in the log file to find errors as explained by Rob Mensching (Wix & Orca author).
Also try to disable any anti virus software and / or desktop security that may be interferring with the file extraction from the MSI's cab file. Is there plenty of disk space? Are there any errors found during a disk scan?
Are you trying to revert to a previous version of Windows Installer? Here is some information: http://support.microsoft.com/?kbid=315346.
I suppose you could use system restore as well, but that would have other side effects.
What is the overall problem? Windows Installer 5 does not seem to introduce anything very controversial: http://msdn.microsoft.com/en-us/library/windows/desktop/dd408114(v=vs.85).aspx

I have unfortunately deleted some important files and folders using 'rm -R ' command in Linux server.
Is there any way to recover?
since answers are disappointing I would like suggest a way in which I got deleted stuff back.
I use an ide to code and accidently I used rm -rf from terminal to remove complete folder. Thanks to ide I recoved it back by reverting the change from ide's local history.
(my ide is intelliJ but all ide's support history backup)
Short answer: You can't. rm removes files blindly, with no concept of 'trash'.
Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i by default, but not all do.
Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete.
In the future, use rm with caution. Either create a del alias that provides interactivity, or use a file manager.
Not possible with standard unix commands. You might have luck with a file recovery utility. Also, be aware, using rm changes the table of contents to mark those blocks as available to be overwritten, so simply using your computer right now risks those blocks being overwritten permanently. If it's critical data, you should turn off the computer before the file sectors gets overwritten. Good luck!

I have a big problem - I managed to accidentally uninstall the whole PostgreSQL DBMS from my hard drive. I also lost my database and haven't made any dumps of the containing data. I do, however, have a backup of all files from the server. Is it possible to somehow restore the database from these files?
The OS I am using is Debian 6, and the DBMS version is PostgreSQL 8.4.
If it is indeed possible, then how should I go about achieving this?
ps. Sorry for my English.
Make sure your backup is safe. So long as we have that we can start again.
Restore the PostgreSQL server software (check package titles)
apt-get install postgresql-8.4 postgresql-client-8.4 postgresql-contrib-8.4
Stop the server
/etc/init.d/postgresql stop
Restore all your data files. Make sure the ownership is correct:
cd /var/lib/postgresql/8.4/
mv main main.OLD
cp -a /path/to/backup/main .
/etc/init.d/postgresql start
Check the logs (/var/log/postgresql/...) - if your backup occurred while the database was idle you are probably in luck.
Note that you need everything in .../main/ - the database files are in main/base but there are the transaction logs and other assorted bits and pieces needed too.
If you get problems, check your permissions, check your postgresql.conf file (restore that from backup too if you have it, pg_hba.conf etc too). There might be some other packages you need to install too if you were using pl/perl or some such earlier
Now. if you get problems complaining about missing log-files or bad blocks then that means the backup happened while the database was writing to the disk and there may be corruption. However, let's be optimistic and hope for the best.
If it works, check everything looks OK and take a pg_dump of any databases you want straight away.

I used maven to download mahout and hadoop recently. Because I could not seem to do that without using sudo mvn commands, eclipse could not seem to be able to use anything I had downloaded (there were lots of errors like parents of things like POM.xml being permission denied etc.) and more recently than that I was trying out mahout (with local jars downloaded directly from one of apache's mirrors, not from maven) and although I could run the class the first time, I couldn't do it again because my eclipse instance could not overwrite the file I had already written.
These are just examples of times I feel it would have been good to be running eclipse as superuser by doing
sudo eclipse
Instead of just launching it normally. The only problem I can think of is that as root eclipse suggests you use the root/workspace, but is it ok to just tell it to use yourusername/workspace?
In general- no. It's tempting, but not very good practice to do all of your development as the superuser. If you're running Eclipse as root, then you're also launching Java processes as root when you run your software. (You could change your Java run settings to sudo back to a regular user before running, but I wouldn't recommend that as a solution).
In addition to being a security risk, you are also making it difficult to track down bugs if you want to distribute the software to others to run as non-root (e.g. doing root only things like reading a protected file or using a well known port might work for you, but not for the average user).
I recommend finding the files that are causing issues and doing chmod o+r on them.

Been trying to install Postgres version 9.2.4-1 on my desktop (Vista x32). Downloaded the installer but upon running the .exe a blank window came up with the installer name as title.
This was strange as the installer worked fine on my office pc, also running vista x32. I've tried googling but there are no solutions abound. I've tried the following steps:-
redownloaded the installer. no dice.
downloaded older versions of the installer and the x64 version (same problem)
fully updated vista.
ensured admin rights
tried running from command line.
disabled UAC and windows firewall.
event logs did not show anything nor was there an install-postgresql.log in the %temp% folder.
Disabled antivirus
Followed the FAQ on common installation errors.
my user variable PATH:
C:\RailsInstaller\Git\cmd;C:\RailsInstaller\Ruby1.9.3\bin;C:\Program Files\Java\jdk1.7.0_15\bin;C:\Program Files\MySQL\MySQL Server 5.6\lib
been going crazy trying to figure this out! please help.
As the installation is hung\incomplete in your case install log names should be bitrock_installer.log or bitrock_installer_xxx.log, where xxx is a number (the process ID of the installation attempt). Please check the %temp% dir for this file. This will log all manner of data about the installation, and is invaluable when troubleshooting. The log will be called install-postgresql.log if the installation completed successfully. If not, the installer may not have been able to rename it, in which case the name will be either bitrock_installer.log or bitrock_installer_xxx.log, where xxx is a number.
SOLVED!
right click on .exe
run as administrator
Apparently running the installer on an administrator account wasn't enough. Which was odd as I could just run the installer on my office pc without jumping through this additional hoop. Can't believe I just spent hours on this non-issue!
Thanks for the quick responses!

I want to install the PowerShell Community Extensions using only the command-line.
I don't want to use a UI, no right-click extract, double-clicking an MSI file. I have to do this process on dozens of computers. However, all of the instructions I've found involve all of this clicking and downloading.
I'm looking for a series of PowerShell commands that can complete the installation. Ideal solution would be completely self-contained: download file X & install. I would like to avoid copying local versions to the given server.
Requirement of Admin access is fine.
Clarifications:
I'm starting from a blank computer, with PoSH 2.0 installed. I'm logged in via PsSession.
I'm looking for a series of PoSH commands, not a list of instructions.
I'm actively trying to avoid "Open IE and download a file", that's the anti-thesis of a shell.
Edit for 2014
I would now do this with Chocolatey.
Chocolatey has a one-line download & install command followed by an additional command in to install PSCX.
PSCX (2.0) is available as a zip and all you have to do is copy the contents of the zip file to your modules folder -$env:Home\Documents\WindowsPowerShell\Modules ( for user) or $PSHome\Modules (for system) - and when you want to use it, issue import-module pscx.
Read the release notes for more details.
