Tomorrow I'll try to do full install of prepare 3d
As I suspected Checksum doesn't match
1) Download p3d full size package properly by a download manager
2) After that check Checksum ZIP file's if match
3) Then run P3d.exe as administrator, disable my norton antivirus.
I let you know if this work, at 99% i did something wrong in the installation process
One more question I need to disable Norton only when i run P3d.exe, and when i'm activating right ?
When I download the package I also need to disable norton ?
Best regards
Your plan sounds good.
Notes:
Delete the last download with the bad checksum.
Also, Uninstall add-ons, then uninstall P3D and any old P3D folders left behind.P3D
I shut off my Antivirus during Download, checking Checksum run P3D setup (full install to my C drive C:\Lockheed Martin\Prepar3D v4) reboot PC, verify Virus checker back on.
Test P3D in a default state.
Do not add your add-ons until all is running properly.
Follow Poppet's guides.
Good Luck.
