Hi Accounts1977
The error log mentions this specific error, " System.InvalidCastException: Unable to cast COM object of type 'Microsoft.Office.Interop"
Generally, this error means that when a program such as AccountRight asks which version of Outlook is installed, the wrong version is being reported back, causing a communication problem and errors between the programs. This can happen when different versions of Office may have been previously installed on the computer, and components/values are left behind.
There is a range of interop errors, these most often are fixed by one of the following:
1. Quick Repair office. (any missing files should be added back), if it doesn't work, move to the next step.
2. Re-install Microsoft Outlook. ( If this doesn't work either, please follow the next step).
3. Re-Register DLL files and Check/Fix Registry Keys (there are 3 to complete)
3. Re-Register DLL files and Check/Fix Registry Keys (there are 3 to complete)
Step 3 would require an IT Professional as its an environmental issue, with windows having missing or incorrect information and this help article has similar instructions which might help:
