"unable to authenticate original disk within the time limit" SOLUTION Windows 7 x64 bit (PMDG 747 for FS9)

Today I was installing the PMDG 747 for FS9/FS2004, but I got the error "unable to authenticate original disk within the time limit".

SOLUTION

Do you have any other applications open that are possibly accessing the optical drive that your disk is in?

I bet you have.

In my case I was watching a DVD using Classic Media Player but I also had open Windows Explorer which was accessing the optical drive to show me files.

After closing both applications and clicking on "Try Again", the installation
continued and loaded fine. After starting I was able to resume the other applications and use them as normal.

So click on "Try Again" or by re-running the setup.exe (or autostart.exe) from the disk.

Hope this helped you as it had me confused for an hour.

How to remove (hide) system reserved drive in my computer ...

Few days ago I was helping out a friend install Windows 7. He had the system reserve partition that Windows 7 creates appear in his 'My Computer'. He asked me how to remove it (get rid of it). I said to him it wasn't a good idea to get rid of it as it was there to help boot up Windows 7 just in case of failure. I decided to research it and it turned out you can simply hide it. To hide the system reserve drive from appearing in 'My Computer' do the following:

1) Open Control Panel

2) Open Administrative Tools found in the System and Security Category

3) Open Computer Management

4) Click on Disk Management

5) Right click on the system reserve disk drive and select 'Change Drive letter and Paths ...'

6) Select the drive letter and click on remove

7) Click OK

8) Check that it has been 'hidden' (removed) from My Computer

9) Recommend you do a restart and save a restore point
