IIF file - Error message says: Problem: You are trying to open a QuickBooks file. Only QuickBooks company files can be opened this way? HELP!! I need to work.
Thank you for posting here in the Community, @Kyle57.
I'd be glad to assist you in opening the IIF file.
This error will usually occur when the file association of the .iif file is changed to other applications other than MS Excel. You'll want to verify the type of file you are opening by right-clicking the file and choosing Properties. The file type is listed under Type of File.
If needed, you'll want to change the file association of the .iif file to open with MS Excel. This way, you'll be able to open the file.
