My Excel is broken and I am getting desparate enough to think about upgrading to Office 2016 pro. Currently I have Lenovo t486p OEM Windows 10 pro with Office 2010 pro.
In the last decade I have developed hundreds of Excel Macros, and sometimes I "break" Excel.
Luckily, I've become proficient at fixing the damage, but today I am stumped.
Excel 2010 seems to work fine, but these 2 annoying startup messages appear every time I open excel. They say there is a broken file, but I have no clue which file.
60D48010:: file format is not valid.
70C48010:: file format is not valid.'
If I start Excel in safemode (control key down) the messages do not appear.
The following attempts to fix it all failed. Most of the steps were followed by a reboot.
Deleted everything from XLSTART.
Disabled COM and Excel addins.
Return macro security to highest level. No macros run and f11 shows that the only vbaproject is Book1
"Reinstalled" Excel. (Actually used control panel to modify office to have Excel not available. Then returned it to fully available.
reset office ribbon and QAT.
