- Convert Office 2016/2019 ClickToRun installation licensing from Retail to Volume
which then can be activated easily using various KMS solutions

- All current Office licenses will be cleaned up
then, proper Volume licenses will be installed based on detected Product IDs

- "Mondo" Suite cover all products, if detected, only its licenses will be installed

- "O365ProPlus" Suite will be converted with Mondo licenses by default

- "Professional" Suite will be converted with ProPlus licenses

- If main products SKUs are detected, separate apps licenses will not be installed to avoid duplication

SKUs : O365ProPlus, ProPlus, Professional, Standard, Visio, Project
Apps : Access, Excel, Onenote, Outlook, Powerpoint, Publisher, SkypeForBusiness, Word

O365ProPlus and ProPlus cover all apps
Professional cover all apps except SkypeForBusiness
Standard cover all apps except Access, SkypeForBusiness

- This is not an activator, just a licensing converter

- Office 2019 products are officially blocked on Windows 7 and 8.1
to workaround that, follow these steps:

if you want Office Professional Plus 2019:
1) install O365ProPlusRetail SKU
2) edit Convert-C2R.cmd and set _O365asO2019=1
3) run Convert-C2R.cmd

if you want Project 2019 and/or Visio 2019:
1) install desired SKU: ProjectProRetail, ProjectStdRetail, VisioProRetail, VisioStdRetail
2) run Convert-C2R.cmd
