Issue installing FNMS on a development server

[nLangTT]

Hi,

Issue: 

• after performing a script based installation of FNMS on an Azure-VM running SQL2019, I have trouble accessing the applications web-ui 
  When accessing http://localhost/Suite all I get is a http-500 error

Question:

• I am unsure how to debug/resolve this and would appreciate if someone could provide suggestion how to get to the root of this issue, or how to obtain additional debug-information/logs.

Hello,

Usually https 500 errors, are internal server error, this may appear if you didn't install all the prerequisites for the application.

Please check is .net is registered

check all the iis roles to be ok

also if you start the webui from the server in the form of https://localhost/suite, may be you will find more information. 

And you can check the iis logs.

Thanks to Adrian's help, I was able to resolve the issue:

It was in fact a missing IIS-Role, and I was able to identify the missing  components using the CheckRoles.ps1 script.

Glad to be helpful, but the way, where can I find this CheckRoles.ps1, I think this would be a useful tool for us as admins, to check if we didn't mist something during installation.

I have obtained the initial Checkroles.ps1 script from Checking FlexNet Manager Suite On-premises application server pre-requisite Windows features - Community (flexera.com)

But in the end I modified a script from Flexera-Spider's Spider-Knownledgebase to cover the roles expected by FNMS. The Spider-script also contains a commandline switch to not only check for roles, but also to install them.
I just had to remove the script signature and change the roles to the FNMS expectations.

Spider Setup: System Requirements - Internet Information Services (IIS) - Community (flexera.com) (needs modification to work with FNMS)

Modified Script:
