I would like to install and use SGP 4.0 but would also like to keep SGP 3.0 just in case I have any issues with 4.0. Is this a problem?
I would like to use the 64 bit version since I am having problems with download of ZWO ASI 071 occasionally hanging. How do I know if my drivers are 64 bit?
I would recommend backing up profiles and sequences prior to using SGP4. There should generally be compatible with each other but I would certainly back things up before proceeding.
I believe the ZWO drivers ship with both 32 and 64bit drivers … you should have both and the transition between the two should be transparent.
