During installation of AppFabric, installation fails with 1603 error.
Installation of AppFabric fails, does not work log shows 1603 error.
There are two possible reasons for this. One is PSModulePath Value is not correct or AS_Observers /AS_Administrators group(s) are available in Local Groups.
Change the value of PSModulePath or just add AS_Observers and AS_Administrators groups to local groups of the machine before running the installation.
To resolve this issue two things we need to verify:
PSModulePath
C:\Windows\System32\WindowsPowerShell\v1.0\Modules
C:\Windows\System32\WindowsPowerShell\v1.0\
Or
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\Modules
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
Local Groups
Once the above two things are verified, rerun the setup again.
