"This advertised application will not be installed because it might be unsafe. Contact your administrator …"

This advertised application will not be installed because it might be unsafe.  Contact your administrator to change the installation user interface option of the package to basic.

Since I am my administrator …  I had to look into why AweSync was not installing on my freshly reimaged work Windows 7 PC.  I’d double click on the installer and it produced the error captured above:
”This advertised application will not be installed because it might be unsafe.  Contact your administrator to change the installation user interface option of the package to basic.”

I consider AweSync a trusted application, and certainly not unsafe.  So a digging we go.  Google wasn’t useful so I ran the install with the following command line:
   msiexec /i "awesync.4.14.0.msi" /lv c:\data\awesync.log
to get a installation log file.

Looking at the log file, the culprit was “ERRCA_UIANDADVERTISED”.  For reasons unknown, the default install settings for AweSync was preventing it from detecting Lotus Notes.  I don’t know why AweSync wasn’t actually installing but I expect that there was some old HKEY Current User registry information hanging around.  Remember how I said I had reimaged my PC?

Running the AweSync with the basic interface option seemed to fix the problem:
   msiexec /i "awesync.4.14.0.msi" /qb /lv c:\data\awesynca2.log

Update:
Since fixing the problem, the best explanation I’ve seen for why running the install with the basic interface option is this:

Running an installer with the basic user interface mode performs only the actions contained in the installer’s Execute sequence and bypasses the error noted above in most cases.
