Upgrade InstallSHield 2018 R2 to 2020 R2 - prerequisite issue

[nirZaken]

Hi, 

I tried to upgrade IS 18 R2 with .Net 4.8 prerequisite to IS 20 R2 with the same prerequisite settings (except the prq "path" and the prq "execute file") and now i'm unable to build the project anymore, i'm getting the following error:

"ISDEV : error -7378: Failed to load selected pre-requisite file:Microsoft .NET Framework 4.8 Web.prq. Check prerequisite file for valid content".

Questions:

does the content of the prq file that i'm using in IS 20 valid?

Should I change the "<file LocalFile=" path in IS 20 prq ?? (see below current path in the build server)

Should I add the "</execute>" at the end of the "<execute file" ?

----------------------------------------------------

--------------------------

This is the current path in the build server contains "ndp48-web.exe": 

"C:\Program Files (x86)\InstallShield\2020 SAB\SetupPrerequisites\Microsoft .net\4.8\Web\ndp48-web.exe"

IS 20 R2 ism file: ISSetupPrerequisites:

<table name="ISSetupPrerequisites">
<col key="yes" def="s72">ISSetupPrerequisites</col>
<col def="S255">ISBuildSourcePath</col>

Question: does the ID in the prq file: "{6EBE6E72-7E5E-4632-A7BB-C8E0387308D0}"
must be equal to ISSetupPrerequisites: "_6EBE6E72_7E5E_4632_A7BB_C8E0387308D0_"
???
