When you have to upgrade your Office installation to 2013 version and using Exact Globe Next version before 406 then you cannot run Excel reports by default.
Office 2013 is not officially supported with Exact Globe Next version prior to 406.
But wait, there is a workaround to make both working, i.e. to run Excel 2013 reports on Exact Globe version 401 for example.
First you should try to install Office2010 on the top of the Office2013 and reinstall Exact Globe Next.
Just install Office 2010 as a second Office version and reinstall Exact Globe.
Then you can uninstall Office2010.
For me it worked for the two of three computers.
If you still cannot run Excel reports, then go to check your Windows registry:
1.Run regedit
2.Go to HKEY_CLASSES_ROOT
3.Check if Excel.Application key is present.
4.If not, create it, and create subkey CLSID
5.Probably as option, but create the second subkey - CurVer
6.Go to HKEY_CLASSES_ROOT\Excel.Application.15\CLSID
7.Copy data value from (Default)
8.Go to Go to HKEY_CLASSES_ROOT\Excel.Application\CLSID
9.Paste data value to (Default) string
10.Restart the computer
11.Run Excel
12.Excel should ask if it should be default application for Excel file types
13.Answer yes, and select all file types as Excel 2013 defaults.
14.Run Exact Globe Next and check if reports works now
