There is no upgrade option with this product. To move to a future version, a new purchase will be necessary.
Office 2021 Professional Plus can be utilised for home, educational, or business purposes. However, if your business undergoes Microsoft audits, we suggest contacting Microsoft directly to inquire about Retail licenses and their compliance in audits.
This license cannot be used on a Server with RDS CALs. Only volume licenses, which we do not sell, are compatible in such scenarios.
This version of Office is compatible only with Windows 10 and Windows 11 computers.
Before installing and activating this software, all other Office editions must be removed from your PC. This includes new PCs pre-installed with a trial version of Office 365.
