I know a lot of people have experienced difficulty getting AIP4Win to run on Windows 10, me included. Some members have managed to get it working, so they may be able to offer advice. Otherwise I know of 2 alternatives. C-Munipack as mentioned in the above post by James, and AstroImageJ.
Richard Lee has been working on a modification to the BAA VSS Photometry Spreadsheet that is used with AIP4Win, so that it will also accept AstroImageJ files. We are in the final stages of testing the new version of the spreadsheet before releasing it. Richard has written an article on the software in the June 2018 edition of the VSS circular.
Would you mind if I retitled this thread to “Photometry Software Issues”? I am thinking this will make it easier to members with similar problems to find it in future.
