If you have NexRemote, HCupdate, MCupdate,PECTool compatibility issues, simply download the latest versions from Celestron’s Manuals/Drivers page. They will work with Windows 7 32-bit and 64-bit systems.
As of March 2010, there are no Windows 7 64-bit drivers for SkyScout. See the SKyScout FAQs for a Windows 7 32-bit workaround.
NexImage also has a workaround for Windows 7 systems. See the article under NexImage FAQs.
Try using the compatibility feature of Windows 7 to install and run your Celestron software. People have had success doing this. We recommend choosing Windows XP 32-bit as the choice for operating system.
Virtual PC running in Windows 7 is another option that has worked. It is a free download from Microsoft. Choose Windows XP 32-bit as the operating system.
VMWare virtual products running Windows images – virtual machines have also had success. Their advantage is they allow the use of USB ports, physical drive locations, etc., which Microsoft virtualization and virtual machines don’t.
