I installed MultiOneTimePasswordCredentialProviderSetup-3.0.701.1530-x64 on Windows Server 20012R2x64, which has a local install of MultiOTP.exe.
First I installed with "Original String" in the "Login Text" box during install. (which is the text prompt shown at login screen).
After locking the active session & testing credential provider works OK, I went back to reinstall/change settings credential provider and also wanted to change the original login text to something else at same time. The installer text box appears to allows me to modify the "Login Text", but the new text isn't actually implemented, and the text still stays as original string. Subsequently, re-running installer still pulls back original string and the changed string is completely discarded and never implemented.
Somehow it's either not detecting that there was a change to "Login Text", or not writing out the new text properly, but either way, the original string value of "Login Text" is effectively stuck and installer won't update it.
Please fix if possible. I'm definitely willing to provide more detail or logs, etc if you'd like. Just let me know what you need/want.
Thanks!
