Fix Disappearing InstallShield Installers by Disabling Windows DEP

The other night I was trying to install Panasonic’s GTWIN on my Windows 7 machine and the installer window would disappear when I got to the installation progress window.  The InstallShield icon would still be present in my taskbar and the processes would still show up in the Processes tab in Windows Task Manager, but the window itself was just gone.

After a bit of googling, I came across a forum post that suggested disabling DEP.  After following this guide on VistaForums, I was able to successfully install GTWIN.

In can be tricky reformatting a Raspberry Pi SD card in Windows 7 due to the multiple partitions that Raspian creates.  Here’s a simple way using the built in Diskpart in Windows 7.

Insert the SD card into an SD card reader and open a Windows command prompt console and start Diskpart.


List all of your disks.

DISKPART> list disk

Select your SD card disk.

DISKPART> select disk <#>

List all of your disks to ensure that the correct disk is selected – the selected disk will have an asterisk next to it.

DISKPART> list disk

Clean the disk.


Create a primary partition.

DISKPART> create partition primary

Create and format the primary filesystem.

DISKPART> format fs=fat32 quick

Assign the disk to a Windowsdrive letter so it shows up in Windows Explorer.

DISKPART> assign

Your disk is now ready for use.
