I was just installing a InfoPath related package for InfoPath 2013, on Windows 8 and I ran into the following error:
Cannot create InfoPath.ExternalApplication object. Error code = 0x80080005
no matter what I did, I could not seem to get around it and there appears to be very little help on the internet for it. I tried the following:
None of the above fixed the problem. I then saw a issue on TechNet relating to InfoPath "How to Use the Query Builder for View Filters and Advanced Searches" (http://support.microsoft.com/kb/307922) and figured I would give that a go.
I altered the reg key to match my version of office:
and created a sub key called "QueryBuilder"
When I restarted the installation of the InfoPath related package, it all installed and ran perfectly. So I thought I would make a note :)
Catch you later.
