My .net windows forms app won't run on Windows 7 64 bit. Error says ADODB not found. Giving it the dll (by putting it in with the program) then gives error that ADODB provider is not properly installed. How to fix this?
The app must run as a 32 bit process as OLEDB is not supported in 64 bit processes.

CR for VS runtime is set for your platform and not the OS.
So if the AppPool of your server is running in 32 bit mode then you need to install the 32 bit MSI, if IIS is in 64 bit mode then the 64 bit runtime needs to be installed.
I am trying to run EasyPHP on Windows 10 (64 bit) system. Initially the error was regarding msvcr110.dll missing, which I resolved somehow. Now its showing the error of 0xc00007b unable to start program correctly. I have tried to run the compatibility troubleshoot as well as run as administrator option. Its just not working. Any other effective solutions ?
This usually happens when you have mix of x86 and x64 libraries installed. You should probably uninstall all x86 versions of Microsoft Visual C++ Redistributables and install their x64 bit counterparts (just google them and make sure you download 64 bit version of that library).
So there is this cool database called firebird, and it can be used embedded. the .net provider (as far as I understand) it uses the fbembed.dll, which comes in 2 flavors: 32 and 64 bits.
How does the .net data provider locates the correct one for the environment that is running in?
It does not select by itself. You have to have that 32bit/64bit dll in the current folder for the provider to load.
If the application is running in 32bit environment (32bit application in 32/64bit OS or AnyCPU application in 32bit OS), the provider will load DLL and expect it to be 32bit. Otherwise you will get bad image format error. Same applies for 64 bit environment.
For this reason, I always create MSI's of my application in two flavours - one with 32 bit dll and other with 64 bit. The application itself remains the same (AnyCPU) so the OS determines what DLL is required. I have been using Firebird embedded for more than 8 years now, and that practice has been easiest for me to follow.
I am running a classic asp page and trying to connect to a postgresql database. I installed the 64 bit and was having issues - then realized need 32 bit because of asp. So did this from ftp.postgresql.org/pub/odbc/versions/msi/…
Now I'm getting
"Specified driver could not be loaded due to system error 5: Access is
denied"
when loading asp page. Went into manager %SystemRoot%\syswow64\odbcad32.exe, but when try to add new DSN, getting
"The setup routines for the PostgreSQL Unicode ODBC Driver could not
be loaded due to a system error code 126: The specified module could
not be found. (C:\Program
Files(x86)\psqoODBC\0903\bil\psqlodbc35W.dll)".
Does anyone know of a good link for step by step setup of a 32 bit postgresql odbc driver because i am having so many issues. Or has anyone else had these issues that might be able to lead me in the right direction?
Thanks so much,
Denise
I ran into the same issue, saw your solution the comments and tried it to no avail, however I did keep searching and fixed it for my situation. It wasn't the 2008 redist but rather the 2010 x86 one for me.
I have created a simple application of reading mail properties from a nsf file using Interop.Domino.dll, things works fine for 32 bit OS but when i attempt to run the same application under 64 bit OS i am unable to create LotusNotes Session , getting the COM Exception. Though i can run the same application on 64 bit by changing the plaform to "x86" but if i change the platform to "Any CPU" its not working.
I have few other dlls which are meanted for 64 bit machine so i need to keep the Platform to "Any CPU", but in this scenerio i am unable to register the Interop.Domino.dll
Is there any Solution to it.
Thanks and Regards,
Haseena
The Domino server api is available in x86 and x64 flavors, so you would need to build against the appropriate one. The client api is x86 only, and if you are linking to that, it would behave the way you describe.
