UPDATE 4: Second Life Viewer is supported on both 32-bit and 64-bit Windows 7 – As of October 2010!
———————————————————————
Currently there is no official SL support for Windows 7 and there is no official windows 7 compatible SL viewer yet. I have heard many SL residents that have been using Windows 7 with no problems at all. However on the other side of the scale there are residents that are having problems with using Second Life on Windows 7 including video card problems, driver problems and so forth.
Some SL residents have experiencing issues and still are having technical issues with the computer CPU usage reaching 100% when using Second Life on Windows 7. The official SL requirements page is outdated and using SLsystest says “Sorry, your operating system does not meet this minimum requirement”. Linden Lab needs to fix this!
Already there are many Windows 7 issues reported on the Second Life JIRA and there many questions being asked about SL on Windows 7 which can be found on Second Life Answers. Just make sure you have good enough specs and make sure you have updated drivers before running SL on Windows 7. If you have problems then submit a JIRA report etc…Second Life is used on all popular operating systems today such as: Microsoft Windows (XP, Vista and now Windows 7), Mac and Linux.
I’m sure in the coming months or next year at some point there will be SL support for Windows 7 and a Windows 7 SL compatible viewer (just like XP, Vista). Just hang in there!
