Any ideas?. After repair, reinstall, etc. same problem.

Hi Sir,

Would you like to share us an English error message? Based on my test in my local environment (Windows 10 & Office 365 pro puls), PowerPivot can work well now, thus, please try this version of Office 365:

Hola, gracias. 
Instalation W10Pro and Office 365 ProPlus in Spanish.
Last versin updated:15.0.4737.1003
"We couldn't load the PowerPivot add-in. First try Office Repair to fix issue. The error below 
should help if that doesn't work.
Could not load file or assembly 'Microsoft.Office.Interop.Excel,
Version=15.0.0.0, Culture=Neutral,
PublicKeyToken=71e9bce111e9429c; or one of its dependencies. 
The system cannot find the file specified."

Hi,

Based on the error message, please try this method:

• Start Excel in Safe Mode ( run: excel \safemode)
• Alt - F11 (opens VBA editor)
• Tools > references
• Un-checked the following:
  • OLE Automation
  • Microsoft Office 15.0 Object Library
• 'Save As'
• Re-open workbook normal

Hope it's helpful.

I've tried in his day and again today, following its: when the workbook is opened again are marked (the safe mode does not save the specified settings).

Added screen. Excellent tool recommended :)
