When we were developing Customized IE7 Setup for a client we faced the following issue and got a work around for this... i thought of sharing with all
Problem:
-------------
We encountered an IEAK issue below:
1. Build a customize IE 7 package with IEAK 7.
2. Install the customize IE 7 in a machine with Beta IE 7 preinstalled.
3. It will uninstall Beta IE 7 first and then restart the machine.
4. After that, IE 7 installation will stop and leave IE 6 on that machine.
If we use the standard IE 7 package from Microsoft site, the IE 7 installation will continue in step #4 above to install IE 7.
Cause:
----------
When we install the customized IE, some of the installation files will be extracted to a temp folder
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\IXP000.TMP before installing. When the installation process uninstalls the IE 7 Beta version and reboot, these temp files will be removed. After rebooting, customize IE 7 installation cannot continue due to the missing of the temp files.
This issue only occurs with customize IE 7. For standard IE 7 package, these temp files are not needed so IE 7 installation can continue after rebooting.
Resolution:
------------------
We have several workarounds for this issue and we choose the one below finally:
Written code in detecting what version is installed in an users machine using VB and then integrated in IE7 Setup. If user is having lower or beta version then our code will run and prompt user to uninstall it manually.
