How to install Office 2010 and Office 2003 on the same system

Why do you want Office 2010 and Office 2003 to coexist? Answer: User needs! There must be a solution if there is demand. I finally found a solution in the vision, thank Ziy friends!

The following is the original text:

After two office installations have been installed, run the following two commands in run to resolve the problem that requires a long wait when you open two versions of Office alternately:

REG ADD hkcu\software\microsoft\office\11.0\word\options/v norereg/t reg_dword/d 1

REG ADD hkcu\software\microsoft\office\14.0\word\options/v norereg/t reg_dword/d 1

Then use the following methods to resolve the default version of the document, spreadsheet, PPT file (that is,. doc file 2003, default 2003 opens,. docx file Default 2010 opens ...). Open word2003, run help-Detect and repair, select Restore shortcuts on repair, and click Start.
