Error while checking for instances

[richakamal]

Hi,

I have recently started working on Installanywhere 2010.
We are trying to migrate our Installshield installer to Installanywhere.
I was looking at the implicit options available for upgrade with Installanywhere. I found that instance management has been added to the Installanywhere which takes care of the upgrade.
I made a sample project with version 8.5.0.0 and then created a higher version build 8.5.1.0.
In the advances settings, I have enabled the maintenance mode support and checked all its available options.
I have enabled Instance Management and limited it to a single instance.
I have selected to identify instance using location and subrevision.

I installed 8.5.0.0.
When I run the installer for 8.5.1.0 it presents me with an option of modifying the existing instance and Installanywhere is able to find the correct instance. But one I go to next step it gives an error saying

An error occured while trying to manage the selected instance.

I ran the installer in debug mode and found the following error messages.

ChooseBundledVMs: Unable to locate the VMPack Directory

Error while checking for instances

Can anybody explaing why this error is coming and how can I correct this?
I do not find this file on the system and why is the Installanywhere looking for a file?
Under the Install tab for the Uninstall $PRODUCT_NAME$ section I see there is an option to edit Uninstaller properties. Is it this same file? Do I need to configure it differently?

Wow. This is really nice information. I have kept a note of it.
The issue indeed was because my Create Uninstaller action was referring to Common component instead of the uninstall component.
But now I face another issue 😞
When I select the add features, it takes me to the Choose Install set panel. But all the features and next button are disabled there.
I changed the product version and a component version and also updated a file. Even then it is always coming as disabled. How do I proceed ahead with the installation now?

Please let me know where will this Uninstaller action will be??
