V26 will install on Windows 10 but does not execute. I brought out my older Windows 7 laptop, spent over an hour downloading v26.01 and installing. Once done, I was able to go online with the processor and upload the existing application.
Would be nice if A-B admitted that something doesn't work rather than just (as usual) assuming that the user will automatically update to the latest version. At version 31 there is either a serious issue with the platform or they are adding features before they are properly tested.
Hope this note helps others.
