Cause:<\/strong> In principle, the problem with all Office versions (including Visio and Project) is that you must always have the same versions if they are to be installed in parallel on one system. There are two variants.<\/p>\n\n\n\n

The first is the \u201cclick and go\u201d variant, which does not require a Microsoft account for activation and is always activated within the program itself.<\/p>\n\n\n\n

Examples of this are our:<\/strong><\/p>\n\n\n\n

OFFICE PROFESSIONAL PLUS 2010 \u2013 2021<\/p>\n\n\n\n

OFFICE STANDARD 2010 \u2013 2021<\/p>\n\n\n\n

VISIO PROFESSIONAL 2016 \u2013 2021<\/p>\n\n\n\n

PROJECT PROFESSIONAL 2016 \u2013 2021<\/p>\n\n\n\n

The second option is the retail versions. These are registered in your Microsoft account at https:\/\/setup.office.com\/<\/a> (marked with a chain symbol in our shop) or activated in the program itself (without a chain symbol). However, both types require a Microsoft account. Examples of this are:<\/p>\n\n\n\n

OFFICE PROFESSIONAL PLUS RETAIL BOUND 2019 & 2021<\/p>\n\n\n\n

OFFICE PRO PLUS RETAIL<\/p>\n\n\n\n

OFFICE HOME & BUSINESS BOUND 2016 \u2013 2021<\/p>\n\n\n\n

VISIO PROFESSIONAL RETAIL 2016 \u2013 2021<\/p>\n\n\n\n

PROJECT PROFESSIONAL RETAIL 2016 \u2013 2021<\/p>\n\n\n\n

Solution:<\/strong><\/p>\n\n\n\n

The program to be installed must be replaced with the \u201cClick and Go\u201d version, or the installed program must be replaced with the retail version.<\/p>\n","protected":false},"excerpt":{"rendered":"
