Hi

Is running application developed in PB2021 1509 in Windows Vista R2 officially supported?

It seems to be working with these exceptions:

  • WebBrowserSet or WebBrowserGet crash instantly in pbvm.dll with exception c0000005 at offset 0x00058f84
  • Webbrowse object doesn't work at all
  • .Net Dll works after installing .NET 4.6.2 runtime and adding netstandard.dll to GAC
     PBClient Launcher installer bricks at the begining of the installation process. It looks like it is not able to invoke the elevated privileges dialog.

Hi, Tomas - 

It's not officially supported. Windows 8.1 is the minimum supported version of Windows.

Hi

Just FYI if someone will solve Vista issues in the future:

1. Forget about webbrowse object. It's not possible to run it.

2. Don't use WebBrowserGet / WebBrowserSet on Vista

3. Install .NET 4.6.2. It's tricky but it's possible. The process is here:

  • Start the installer
  • Continue until it fails
  • Copy the newly created folder c:\0f4d9d6fdc6ca4f7eb0ab719fa2c337b or similar weird name
  • Close the installer
  • Run netfx64_full.msi (or 32bit for 32bit version of Vista)
  • Go to Control panel -> Remove apps. Locate "Microsoft .NET framework 4.6.2" and rightclick "Change or remove"
  • Select "Repair"

4. If you use .NET: Look for netstandard.dll and add it to GAC with gacutil (from NETFX 4.6.2 Tools).If it's missing use your own netstandard.dll (4.6.26011.1 - 96.3kb works)

gacutil /i "C:\Program Files\dotnet\packs\Microsoft.NETCore.App.Ref\6.0.4\ref\net6.0\netstandard.dll"

gacutil -l must return:

"The Global Assembly Cache contains the following assemblies:
  netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51, processorArchitecture=MSIL"

Adding to what John said, since it is not officially supported it is possible some features will not work correctly, especially any new features Appeon added to PowerBuilder, such as the Chromium WebBrowser control.

Microsoft no longer supports Vista either ...
