I installed JCL/JVCL in my Delphi 10 Seattle, first from getit, later manually. I cannot install the jvPluginSystem design package. All packages work well but this design package produces an EAccessVialolation in jclDeveloperTools. I double checked for multiple instances of dcu's and bpl's and also tried on a freshly baught Windows 10 Surface pro without any other Delphi versions. Same result. I also checked that unitversioning is off in JCL and JVCL and did a complete build of the packages.

I suspect that it came either with the latest Delphi Update 1 for Seattle or it is a Windows 10 related issue. Did anyone also experience this Problem?

I used Version 3.4.9 Complete Package (including JCL) from Sourceforge.

  • You can debug the IDE and find where this crashes. Are you familiar with the technique? Example: http://stackoverflow.com/questions/14532835/error-starting-delphi-when-debugging-design-time-package – Warren P Dec 07 '15 at 20:56
  • Thanks a lot, I was not aware of this and will try it today! – MichaSchumann Dec 08 '15 at 13:04
  • You can in some cases even launch delphi, wait for the crash, then attach the debugger, but usually it's better to attach before the exception or else start the ide. I plan to write a detailed tutorial on my Delphi Code MOnkey blog on this subject soon. – Warren P Dec 08 '15 at 14:04
  • @Warren: Sounds great, looking Forward to reading this tutorial soon! – MichaSchumann Dec 09 '15 at 14:26
  • Solved my issue by reinstallation through getit. But I am interested in generally solving a Problem like this. – MichaSchumann Dec 09 '15 at 14:27
