On client`s PC an error “Cannot launch Excel” appears after opening .exe file and choosing “Original Workbook”

In the alert message header “uni.tmp” is added to the end of the existing file name.

What causes this error?
 
the anti virus or Windows Defender cause that. I get same error. I solved by allow my application at my antivirus software settings under “allowed apps”

also should be allowed at Windows Defender.

Or you can buy a sign and put inside your code to pass Windows Smart Screen so your app will pass as a safe app on any antivirus app i think.
 
The most probable reason is that an antivirus software blocks the execution of Excel. I suggest you to create a pure 64-bit EXE file with XLS Padlock for this client. That will avoid the creation of the temporary process “uni.tmp”.
 
Hi I have a client who is experiencing the same problem where “uni.tmp” is added to the end of the existing file name.

Did you find a solution to this problem?

Thanks Frank
