I am trying to install web adaptor 10.2.2 to my windows server 2012R2 64 bit.But its strange that, i can't execute installation file.
"Your system has not been modified.To complete installation at another time, please run setup again."
Also, I checked Event Logs :
Event ID : 1033
Installation success or error status :1603
I logged in with Administratior account.
I installed all the requirements for web adaptor(IIS,.NET etc.) but i can't fix this.
Could you please help me to install it ?
