I have Excel 2007 in Win7-64. I have placed an Add-in as in my D:\Server Backup 10.05.2015\Backup\Files Needed\Backup folder\Excel 2007 Assistance Tools\Excel Assistant.xlam and yesterday I changed the Add-in path to D:\Server Backup 10.05.2015\Excel 2007 Assistance Tools. As normal the excel 2007 said 'could not be found'. I gave 'ok' and removed the Add-in in Add-in dialog then added it from the new path. However after excel restart again I got 'could not be found' error. I tried remove and add the Add-in several times. I keep getting the error message on Excel start or restart.
Can you help me resolve this?
