Integration Components Setup Error: An error has occurred: Internal Error

leave a comment »

Here’s an interesting one 🙂
You try to install the Hyper-V Integration Services (Drivers) in a VM with Windows 2003 and you get the following error:
An error has occurred: Internal Error

Hum… 😦
No errors in the event log we decided to start by installing the latest updates for that VM. Unfortunately not all updates were able to install properly, in fact most of the updates were failing to install as well…
 Ok, Back to the Integration Components setup, it was time to check the log. Under %Windir% directory we check the installation log “vmguest.log”:

Hyper-V Integration Services Installer version 6.1.7600.16385
MUI file loaded

##### END: INSTALL KMDF – Error code = 0xF00D
Detected worker thread exit
Worker thread error code = 0000F00D
Exit code = 0xEA60

After identifying which component fail, we proceed to the respective log “Wdf01007Inst.log” under the same directory “%WinDir%”. Inside this log, between other errors, we found this one:
Failed to copy spupdsvc.exe

So we decided to analyze the “%Windir%\System32\ spupdsvc.exe“. After checking the ” spupdsvc.exe” we discover that “spupdsvc.exe” did not appear to be a original Microsoft exe file, we were able to confirm this checking the “spupdsvc.exe” properties and its digital signature which didn’t exist at all.

The Solution was to delete the “spupdsvc.exe”, run a Malware remover tool in the system (this may be need as the antivirus may not be able to detect the malware or remove it), then copy the “spupdsvc.exe” from a healthy system to the problematic one.
After this the Integration components were successfully installed and the updates that were also ALL installed successfully.

Wouldn’t it be handy to have one place on the web where you could find an updated list of ALL the AV exclusions you might want to configure? This wiki stub topic is meant to be that list. Feel free to add to the list, it is the wiki way!
