Turns out a workaround is to log in as a different operating system user on the machine where this is happening, run the program, then return to the original user, so using that for now.
How did you even manage to download/install FlashBuilder 4.7?
I recently got a new Win10 machine, and still have the license for FlashBuilder 4.7 that was used on my previous machine.
However, I am not able to get hold of a FlashBuilder 4.7 application.
If I try to download FlashBuilder 4.7 Standard, I am just redirected to some kind of payment page for upgrade?!?
If I try to download FlashBuilder 4.7 Premium trial version, I just get "Page not found" error
If I try to contact Adobe support, I do not find FlashBuilder as a product
Hmm you used to be able to get it at https://creative.adobe.com/products/download/flash-builder but looks like that is broken now. It might work if you go through the buy process (click buy now here Adobe Flash Builder 4.7 Standard) and then get a refund, but I'm not sure.
You might have to find a third party site that has the installer.
