I highly appreciate your effort, and you fulfilled your promise of updating the program on this Thursday. So i thought the unable to detect programs issue was fixed, turns out it is partly fixed. In version 2.1, i planned to test the power of Uninstlar, so i downloaded multiple apps from a company that's famous for making bundle ware and apps that are very difficult to uninstall, apps from https://www.360.cn . But Uninstalr was unable to detect them, i waited until the 2.2 update and tried it again, Uninstlar is still not able to detect it. So i tried another infamous bundle ware company: https://www.2345.com/product/ . Uninstlar was able to detect and uninstall, but lots of remaining files can be found in programs files(x86).
Note: these 2 company make security and computer monitoring softwares, so they have very high privileges to control Windows, that might be the reason Uninstlar was unable to clean it completely. I used a virtual machine to test Uninstalr, that might also be the reason why Uninstlar wasn't able to detect some apps. And i highly recommend you to use virtual machine, as the above 2 is infamous is no joke, you won't want to try it on your actual computer. It's just a little challenge i give to Uninstlar, to test the uninstalling power, i don't expect a mandatory fix or improvement made just to uninstall the above 2.
