Hi Jenifer, I really appreciate your help. For some reasons (I do not know if rebooting, relaunching, etc was responsible), "Edit prerequisite" item is enabled now: "Show details" button you mentioned works as it should, it shows details for the selected prerequisite. " Microsoft Visual C++ 2015 Redistributable (x86) " was successfully downloaded.  "Edit" is enabled for it. "N ew pre-requisite using Prerequisite editor " may be created and edited. This means that the issue seems resolved, at least for now. It is not clear what caused it, though.  Thanks again, Ilia.   ... View more

Hi, Jenifer. We are using InstallShield 2016 Professional Edition version 23 Service pack 2. Suspecting possible permission restrictions we reinstalled it on drive 😧 instead of C:.  "Edit prerequisite" as well as several other options still are disabled, in the same way. Unfortunately, the software does not allow running setup simultaneously on old and new machine ("trial period expired" ) even if we uninstall/install IS on old machine.  I attached two setup files, old and new one in hope this may help. Build is successful on both machines.    Thanks, Ilia. ... View more

Yes, both are 2016 Professional editions. How did you transfer .prq files? - Don't remember for sure, but most probably I copied them to the same location on new machine. Did you do file comparision of both the .prq files between two machines? The files are the same. For  "Microsoft Visual C++ 2015 Redistributable Package (x86).prq" contents is  <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <SetupPrereq> <conditions> <condition Type="32" Comparison="2" Path="HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DevDiv\VC\Servicing\14.0\RuntimeMinimum" FileName="UpdateVersion" ReturnValue="14.0.23026"/> </conditions> <files> <file LocalFile=".\VC 2015 Redist\vc_redist.x86.exe" URL="https://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x86.exe" CheckSum="1A15E6606BAC9647E7AD3CAA543377CF" FileSize="0,13767776"/> </files> <execute file="vc_redist.x86.exe" cmdline="/q" cmdlinesilent="/q" returncodetoreboot="1641,3010"/> <properties Id="{29AE0051-88F8-4ED7-A6F9-7EA37A6B11A3}" Description="This prerequisite installs the Microsoft Visual C++ 2015 Runtime Libraries (x86).

And, remember, "Edit prerequisite" is disabled for all prerequisites. If nothing helps, sharing project files would help us check further. - That's great, but  I could not find option to attach files. How can we share projects? Thanks,      Ilia. </files> ...

Thanks, Jenifer. Tools->Options->Prerequisites are set as: And below is contents of the folder mentioned: I see nothing wrong here. Did not try yet direct using Tools->Prerequisite editor, but all the conditions which where set on old machine are empty there... In any case I'd prefer to work old way, with "Edit prerequisite" item enabled. Is it really impossible? Thanks, Ilia. ... View more

Thanks, Jenifer.  <ISProductFolder> value displayed in Media/Path variables window is" C:\Program Files (x86)\InstallShield\2016\" (without quotes), the directory where Installshield is installed: Is this correct?  At the same time "Edit prerequisite" item is disabled for all redistributables I tried. Thanks, Ilia. ... View more

Thanks, Jenifer. Yes, the prerequisite exists in …SetupPrerequisites folder.  However, the item is disabled. Please see crop of screenshot. Just in case, contents of the file is shown too. ... View more
