Maya 2015 Extension 1 will not install

[zwickarr]

Im running Maya 2015 sp4 on a floating licence. I run the setup.exe and everything seems to install fine...green check marks. no errors, etc.  

I load up Maya and on the splash screen it still reads "Autodesk Maya 2015 Service Pack 4", I dont have any of the new features that get installed with EXT1. not sure what is going on. 

Tried the following:

• disabling startup services/processes for extranneous items (diagnostic startup), then reinstalling
• performing full uninstall/reinstall of Maya
• this includes removing registry entries and trying the MS Fixit tool for full removal
• copying the installed files from another source
• performing repair of extension 1 after installation
• installing the SP4 update and extension individually

don´t really get what and in which order you are doing it but you don´t need to install sp4 prior to the extension 1 because ext1 includes all the service packs. and i´m pretty sure you should not install sp4 after you run the patch for the ext1. didn´t try but sounds like if you do/did this you patch it back to sp4 only if this is possible. so correct order Maya2015 sp doesn´t matter > run extension 1 patch. done!

thanks for the reply sebastian. Unfortinately I also tried installing up to SP3 then installing the EXT1 with SP4 and it didnt work.

Hello zwickarr,

I just encountered this issue today and in the case I encountered the root cause was a MAYA_LOCATION environment variable that was set but pointing to the path of a previous Maya Install. You may just want to delete that variable and reboot the system and then try the install again. If Maya extension already shows on your list of installed programs you will need to uninstall it first.
