After years of successfully installing CE, I uninstalled my Studio in response to a recent email regarding 20.4.
Neither version of CE 20.4 (stable or preview) will install. Unhelpfully, there are no error messages of any kind. The installer appears to change my color scheme to Win7 Basic, then fails.
My settings from %userprofile%\AppData\Local\UiPath are safely copied to another location, per instructions.
I have downloaded each version three times and attempted to install each twice (as Administrator and as a normal user). The result is always the same.
Perhaps a reboot is required, which I will attempt now. I will also try on a Win10 machine, to see if perhaps support for Win7 is gone.
EDIT: Reboot did not solve anything on Win7 Pro 64-bit. CE installed on a Win10 machine (first install) without issue. RE-EDIT: I get a crash dump of approximately 442kb (varies each time) when I attempt installation. No error messages are generated. I would be happy to provide a UiPathStudioSetup.exe.****.dmp file if it would be of any use.
