My problem is the same that this one: https://dba.stackexchange.com/questions/253777/is-it-possible-to-run-multiple-versions-of-mysql-workbench
I need to use mysql workbench 8 for mysql server version 8.0.27 and mysql workbench 6 for a version 5 mysql server.
The problem is that when installing workbench 8 it deletes existing workbench with lower version.
I've tried to install Workbench6 on a completely different location to see if the installation does not find it but I it finds it anyway.
Also tried to install a 32 bit version of workbench 6 but again, version 8 delete it when installing.
Found some comments saying to enable multiple instances in menu -> edit -> preferences -> others, but this is only to open multiple instances of the same version.
I've looked for a portable version of workbench 6 but had no luck.
I don't understand why this problem is not having an answer by MySQL, even the MySQL forum doesnt have a solution or even an explanation why this is not possible.
I use a Vm for that porpose. where an "old 5.7.xx is installed alongside a workbench 6.3that work with that well, because the newer version don't do.
You can use for that purpose also a linux server as vm not only windows
Found a portable version of Workbench 5.2.47. I've upload it to my github.
Although I use this software with no problems until now, this is not from my authorship, use it at your own risk.
Download latest zip archive (version 6.3.8 and earlier has it) from here: https://downloads.mysql.com/archives/workbench/
Look out because x64 archive wasn't working in my case but 32bit works fine.
Unzip to different folder and that's it.
I have recently installed PostgreSQL to my Windows 10 following this tutorial. When I completed the installation, I failed to launch the SQL shell -- I could only see the pgAdmin interface in my installation. I uninstalled and installed PostgreSQL a few times, and the result was always the same. Would anyone be able to help with figuring out how can I get access to the SQL shell?
Thank you!
On my Windows 10, I used the Windows installer made by EnterpriseBD and installed postgresql 11.1. It however seems to have came with version 3.5 of pgAdmin 4. So, I downloaded pgAdmin 4 version 4.0 and installed it on my PC. Now both the two versions exist on the PC.
Did I do anything wrong during installation? How can I remove the version 3.5 of pgAdmin 4 properly?
Thanks in advance for any help.
Go to Programs and Features -> postgresql 11 and click uninstall. A window opens and allows you to select uninstalling whole postgresql or individual components. You can select pgadmin from there.
Hope it helps :)
My MongoDB Compass won't launch. It was working an hour ago, but now it just shows this screen forever.
I've tried rebooting. And even uninstalling and re-installing Compass. But every time I launch it, it just shows the loading screen and never proceeds. If I go to Connect > Connect to..., it just opens another window that does the same thing.
Version 1.10.9
Windows 10 x64
How can I get this program to launch correctly? What should I investigate to try to figure this out?
Had the same issue today, with the Version 1.10.9 on Mac OSX. I then reinstalled MongoDB Compass Community Edition to the latest Beta version (Version 1.11.0-beta.1), the loading proceeded and everything went fine.
Same here. I tried uninstalling/reinstalling. No joy.
I reinstalled an older version 1.8.2 which worked fine. Must be an issue with the latest release.
Edit: I upgraded to 1.10.9 this morning and reverted to 1.8.2 after coming across this issue.
After having the same issue today (november 24:th) i used the latest stable version (1.10.10) and it solved the problem. I´m on Mac OS Sierra (10.12.6).
On window 7, i found the issue was because of two reason and both were related to power shell.
First problem was because of execution policy related to power shell script, which can be solved by running the following with administrator privilege.
Set-ExecutionPolicy RemoteSigned
After this, please check the power shell version, in case you are trying to install latest version of mongodb on window 7, power cell version needs to me minimum of 3.0, in my case it was 2.0 and because of that installation was getting stuck. After upgrading power shell to latest, installation went through quickly.
I managed to surprisingly fix this issue by restarting my computer. I was on Ubuntu 18.04, Compass v1.x (somewhere this year).
I understand that the poster is on Windows but this was the first hit on Google.
This seems to be forever error, even in 3.6.3 version, that i've tried today. There are questions about the error everywhere.
The link below
Installation/Update of MongoDB 3.6.2 on Windows Hangs
explains the problem - the install trying to run execute the PowerShell script to download/install MongoDB Compass, which seems to hang due to insufficient rights.
DO NOT install Compass, or install it later with appropriate rights.
The same problem here.
My MongoDB version v4.2.1, compass-1.23 on Win 10 OS.
In MongoDB Compass screen panel, I went to View-> Toggle DevTools.
In Console section there was error indication in red :
"""Error: Command failed: powershell (...'powershell' is not recognized as an internal ..."""
Powershell can be added to environment variables paths:
Please check this:
Powershell' is not recognized as an internal or external command, operable program or batch file
So, I closed MongoDB Compass window. Then I added path to environment variables:
C:\Windows\System32\WindowsPowerShell\v1.0\
And it solved my problem.
You can also add this line too, to enable MongoDB cmd line commands (your location and version can be different):
C:\Program Files\MongoDB\Server\4.2\bin\

I recently upgraded from MAMP 4.1.1 to MAMP 4.2 on my Mac running MacOS 10.12.6. After upgrading, MAMP 4.2 will not start the MySQL server. Additionally, there is not an option to Stop servers. I see a green box to the right of Apache Server along with the the ability to select Preferences and Start Servers. Open WebStart page is grayed out.
I followed the instructions on MAMP mysql server won't start. No mysql processes are running to delete the ib_logfile0 and ib_logfile1 files from MAMP/db/mysql56, but that did not work. In addition to the ib_logfiles, I also deleted ibdata1 followed by all of the contents of mysql56, but neither of those worked.
Lastly, I do not see a mysqld running in Activity Monitor.
Any help in restoring my MAMP functionality is greatly appreciated. Thank you in advance for any help.
I had the same problem and tried the same things which didn't solved it.
What solved it for me is I tried starting mySQL in terminal manually in Terminal, here:
/Applications/MAMP/bin/startMysql.sh
I saw this error in Terminal prompt:
mysqld_safe error: log-error set to '/Applications/MAMP/logs/mysql_error_log.err', however file don't exists. Create writable for user 'mysql'.
So I manually create a file '/Applications/MAMP/logs/mysql_error_log.err' and retry startMysql.sh, mySQL then started with no problem.
Back to MAMP app console, I can also start/stop servers and 'Open WebStart Page' with no problem now.
