Dealing with "Customization could not be loaded because the application domain could not be created"

Question

I was having the “Customization could not be loaded because the application domain could not be created” problem. This was on a machine which I had just done a clean install of everything. The RTM version of powerpivot would install and run with no problem, but while Powerpivot CTP3 would install it would not start, with VSTO giving the above reason for the failure to load in Excel.

I tried reinstalling and repairing everything, Powerpivot, VSTO, and the dot Net clinet profile… many times, with reboots… and it still would not load. After two days of pulling up my hair, I finally found a solution: it had to do with the installation of dot Net 4, not the installation of VSTO as most people point to as being the problem for this error message. I installed the "full" version of dot Net 4, instead of just the client profile (which is what is indicated as being the requirement)and then Powerpivot started up no problem.

Hi Eric Hutton,

It seem that you want to share some experience about fixing this issue after installing the CTP3 of Denali, firstly many thanks about your sharing, which must be useful to other communities who have the similar issue. However it is not a question, so I change it type to General discussion.

Thanks,
Challen Fu

Thank You! This finally worked!! I had been through every single other "do this" and "try this" there was and I had already done every single stinking one that they had mentioned. installing the FULL .Net framework from that link did it. YAY!!!!!

Answer 5

Glad it worked for you.

Now if I could just figure out how to get PP 2012 RTM  to install properly on a machine with a Domain account... it will only run if I launch Excel using "Run As"and use the local admin account.
