SliQ Invoicing works on Windows 10 as well as all earlier non-server versions of Windows from XP, through Vista, Windows 7, 8 and 8.1.
If you are taking up the offer of a free upgrade to Windows 10 from Microsoft and downloading Windows 10, during installation choose the option to keep your applications and personal data.
The Windows 10 upgrade process makes some identification changes to PCs. You may find that SliQ Invoicing Plus reverts to a trial copy as a result. If SliQ does display its trial notice dialog, press the Register button on the trial notice dialog SliQ displays when it starts and re-enter your unlock code to get back up and running. You can get your unlock code emailed to you via this web page:
We haven’t experienced any problems so far upgrading any of our PCs to Windows 10 with the exception that one of our older printers no longer worked. As no default printer was then selected in Windows 10, SliQ was unable to do a print or a print preview. If this is the case, go into Windows Settings and set a default printer. SliQ will then print and do a print preview OK. You can access Windows 10 Settings by clicking the new Start button at the bottom left of the screen and choosing Settings then accessing the Device and Printer settings option.
