Hi,
Today I tried to install the 3rd Party Update "Adobe Reader 11.0.0.379", first the full version and then the upgrade. Both packages were deployed to 2 computers with Acrobat Reader 10.1.4. On both computers the packages failed to install.

I've searched the WindowsUpdate logs and the Solarwinds Knowledge Base for the code 0x80070643 and found some issues with the PackageBoot. Activated the PackageBoot logging (article on knowledge base) and from the logging file found the following error:
2012/10/19 16:27:30:807 PID: 3720 TID: 2088 ewException caught: The packageboot.xml file could not be found. File: PackageBoot.cppLine: 101 stack trace :
2012/10/19 16:27:30:822 PID: 3720 TID: 2088 _tmain() call failed. Message: ewException caught: The packageboot.xml file could not be found. File: PackageBoot.cppLine: 101 stack trace : . HRESULT: 0x2
Any suggestions?
This is not the first time I had issues with 3rd Party Updates and it seems that PackageBoot might have something to do it but... Lets concentrate on Adobe Reader and then the rest.
