I unfortunately have to say I tried the clean uninstall with Ashampoo, and it did not delete many of the temp folders, so there was much left over.
I try to remember when I used it before, at one time I think it did. Maybe something changed on my system or in Ashampoo, or maybe I did something wrong or missed something.
If it does not fully remove leftover files connected to streamfab, then it's not a clean uninstall.
I did a search on my computer with a great free Windows program Search Everything and searched for streamfab, and deleted all folders that came up.
A very fast and free search program once used you will never use Winblows search again.
I hope to try again soon with Ashampoo if not I may try and go back to BCUninstaller and see what happens.
What I don't do is do it every update, and streamfab runs good. I do it when streamfab seems to do one of many things, like crashes, gets slow or gets stuck analyzing.
It seems always downloading and using the full offline installer has a big effect on how streamfab works.
I am not sure if I ever liked Revo, as I hate programs that want me to pay (for a pro version), when free alternatives are available. Total Uninstaller I just looked and talks about paying but is reasonable($29.95) and 'lifetime'. There are many if people look, I even know for some time I used HiBit Uninstaller.
I have seen many having analyzing issues and many can be fixed by just deleting all contents of streamfabs temp folder. Yes, unfortunately, doing most of this you have to log back into the provider's that require log in to download. But if you want streamfab to work and work right, sometimes it has to be done. I have talked before, I was lucky to get access to at least 2 other programs that download/record from most providers. Even the main one of them told me I need to clear cache to get an issue fixed, I did not believe it till I tried and it worked. The best of all, it can be done from the program. YES, the program had an option to clear its own cache, no having to find to locate the folder and delete contents.
It just always crazy how some never or barely have an issue and then when some are posted it can not in any way be recreated. Yes, there are exceptions, Location is always a top issue. Using a VPN, no way streamfab can support that or be responsible if you use them and the program don't work properly. There is no one definitive answer, as to get streamfab working if you do have issues, as there are many. Even firewall and antivirus effects it. Network and more.
Streamfab works most times, as always the stream providers are making changes and some programs release intermediate patches or updates, streamfab seems to stick to mostly weekly.
Keeping streamfab up to date as well as your OS is a big part as well.
