Cannot log in to the administration console

If you cannot log in to the administration console with a valid administrator account then the issue will be probably related to the missing "vcruntime140.dll" library.

By default, process config.exe looking for the libraries in the destination below:
C:\Program Files (x86)\IceWarp Remote Console\13.0.0.3\
C:\Windows\SysWOW64\
C:\Windows\System\
C:\Windows\
C:\Windows\SysWOW64\wbem\
C:\Windows\SysWOW64\WindowsPowerShell\v1.0\
C:\Windows\SysWOW64\OpenSSH\
C:\Users\Admin\AppData\Local\Microsoft\WindowsApps\

If the process config.exe cannot find request .dll in any of this path then it will fail with the following error:
SYSTEM [1A70] 09:13:47 Cannot load library: libssl-1_1.dll
SYSTEM [1A70] 09:13:47 Cannot load library: libcrypto-1_1.dll

Logs from the administration console are saved by default in C:\Program Files (x86)\IceWarp Remote Console\13.0.0.3\logs.

To fix the issue download and install Microsoft Visual C++ Redistributable (both x86 and x64) on the link below:
