Symptoms

Using the command

installRnt64.exe /quiet INSTALLDIR="C:\MyFolder\" RegisterCOM=Yes LICENSESRV=Yes WIBUDR=No

Software is not being installed and nothing is happening. 

If /quiet was not used error message "Illegal character in path" is shown

Resolution

The first step to recognize the issue will be removing /quiet from the line this will allow the installer to output an error message on which the issue can be determined. 

As well in our case command

installRnt64.exe INSTALLDIR="C:\MyFolder\" RegisterCOM=Yes LICENSESRV=Yes WIBUDR=No

was used, we need to pay attention to the path specified in the line as an additional slash will be recognized as "Path to the folder" which is not specified resulting in the error message "Illegal character in path"
