Hi all,

 

When I try to install the curse gaming addon client it attempts to update .Net 3.5 profile and promptly fails with a series of popups that say dfshsim.dll is corrupt/not a windows application (screenshots attached).

 

I ran sfc /scannow which also identified both dfshim.dll and netfxperf.dll as corrupt but was unable to restore them because the sources are also corrupt:

2014-04-10 23:34:52, Info CSI 00000638 [SR] Could not reproject corrupted file [ml:48{24},l:46{23}]"\??\C:\Windows\SysWOW64"\[l:20{10}]"dfshim.dll"; source file in store is also corrupted

2014-04-10 23:34:52, Info CSI 0000063e [SR] Could not reproject corrupted file [ml:520{260},l:46{23}]"\??\C:\Windows\System32"\[l:20{10}]"dfshim.dll"; source file in store is also corrupted

 

I've tried uninstalling and re-installing .Net 4.5, running chdsk /F and cleaning registry using CCleaner and none of them have solved it.

 

My computer doesn't have any symptoms of a virus/malware infection. I've run both MalwareBytes and MSE and they both came back clean.

 

Any advice on how to restore these .dlls?

 

Thanks,

djclerik

Hello,

 

Try to extract them from the installation DVD:

Thanks Georgi for your quick reply!

 

Following the steps in the link in your post for all 3 of the corrupted .dlls fixed my problem. I ran sfc /scannow again after copying the recovered dlls over and it returned: "Windows Resource Protection did not find any integrity violations."
