Msi.dll not working

[Falzarg]

Dear, 

Yesterday evening a Windows Update went wrong. I suppose the desktop stopped working while still updating. (error code : 0x800706be)

Since that moment I get this : C:\Windows\System32\msi.dll is not suitable for windows or contains an error. Try to reinstall.. errorcode : 0xc000012f. I get this for both Java and Adobe, and of course multiple other apps. 

I don't know what to do anymore : cmd is limited (no use of sfc, chkdsk,..), resets also don't work,..

Can someone help?

Hey WAWood,

Thanks for your solution! I cannot confirm this works.

I eventually got help from the HP support and did a complete reset using HP Cloud Recovery Tool on USB.
