Hello forum,

Yesterday, I received the above error message. It indicated that I should reinstall the software to fix the problem. After installing the new software for 10 minutes, VCDS started up... everything was working fine again.
Today I want to read different values, but VCDS is reporting the same error as yesterday. I would like to avoid having to reinstall it every time before using it.

Although VCDS reports that the file is missing, I find it twice.
on the computer, in various folders.

WIN7 64-bit.
VCDS HEX - Version 2.

Does anyone have a workaround?

Hello,

The .dll file usually belongs in the same folder as VCDS.exe, so that the .exe file can find it.
I suspect a rogue antivirus scanner that is blocking access or quarantining the .dll file.

Best regards, Rainer.
