Issue

Nitro PDF Pro (v10.5.8.44) virtual PDF printer disappeared from the list of installed printers on some Windows 7 Pro PCs. Re-installing it via Nitro PDF Software Support Tools (located in C:\Program Files\Nitro\Pro 10\NitroPDFSupportTools.exe) fails with following error:

Nitro PDF Software Support Implements
Installer of the printer driver failed.

Resolution

I contacted Nitro PDF share regarding this one. Theirs response were that a recent Windows How produced more changes Print Spooler service which breaks Nitro PDF Creator printer driver. Nitro resolved the issue the version 10.5.9.9. Advanced Nitro PDF Pro to this version restored the PDF Creator printer on all affected PCs.
