Hi, I’m a windows 7 user with 64 bit architecture. I’m using outlook 2007 version for my email needs. I have made an add in for outlook. I’m able to successfully install the program without any issues, but once I start the outlook. I get this error message “ Downloading file:///C:/Users/paro/AppData/Roaming/Tekla. Oyj/OutlookAddInSetup/CRM_OutlookClient_Change.vsto did not succeed.” Please help me find a solution to this problem. Thank you.
