.Net framework won't work for 32bit programs in Win7 64bit

Hello,

I am having issues with programs depending on .net framework. (Twitch Desktop & others)

When launching the programme, an error appears directly :

- "Application unable to start correctly 0xc0000135".

Some dependency walker job shows me that the mscoree.dll is not found for the sepecific exe.

Environment :

Windows 7 64bit
.Net Framework 4.7 freshly installed

What I did:

- Uninstalled all .Net framework and reinstalled the 4.7 pack
* didn't fix the issue
- Cmd (as admin) then "sfc /scannow"
* log says multiple times that some mscoree.dll version mismatch
* log says multiple times that some mscoree.dll source also corrupted
* didn't fix the issue

What I know :

- All programmes (2 for now) having the same issues are 32bit programmes based on .Net framework.
- There is a mscoree.dll in system32, but none in SysWOW64

What I am doing:

- .Net is corrupted and needs to be forcely reset.
- I lauched the following command before leaving home
* DISM.exe /Online /Cleanup-image /Restorehealth
* Use the System File Checker tool to repair missing or corrupted system files


Could anyone give me some ideas about how to solve this issue ?

Best regards

Hi,

Thank you for your reply.
I didn't work as you said.
I also tried to repair the whole system with my installation DVD. Strangely it said "system recovery not compatible"
Just before thinking of reinstalling Windows, I tried the worst possible solution:
I downloaded a 32bit mscoree.dll for x64 Windows 7 and copied it to SysWOW64
And it worked...

I didn't say Net Framework would WOULD work I said TRY!
...
And if it DIDN'T work post CBS.log which you didn't!

You were fortunate that mscoree.dll is identical in both SysWOW64 and System32
...
Please mark this tread as resolved!

Hi Snick,

I feel confused how you looked so triggered by nothing at all.

I was actually saying that, DISM.exe did not work, same as you suggested in your earlier post. Should have been more clear in my words.

And I know reinstalling windows is a bad idea, that's why I was looking for other solutions.

I was not fortunate. Instead I know SysWOW64 contains 32bits dlls for 64bit OS. That's why I looked for a 32bit version of mscoree.dll, AS I SAID in my last post, instead of copying the one that sits in my system32 folder.
It looks like you don't really read posts before making an response with countless exclamation marks.

To end the story, the thread was already marked as solved, the moment you were asking me to do that.



I actually feel happy to see people like you actively willing to help others solve practical problems in their daily life. Me being a Window/Linux programmer, is unable to devote myself as you do. I give you all my respect for that.
But please Don't take others as fools. Especially when you don't read what others say. This only makes you one. Arrogance is never a good thing.

Saying that, thank you for your answers.

Best regards
