Is there a way to skip the install readiness checks during the install?

Yes.  Of course skipping the pre-req checks can result in undefined behavior of the product.  But there may be a case, for example, where the CPU speed does not meet the minimum specs even though you have multiple processors.

To disable the check for SIM prerequisites:
Add the key HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM to the registry.
Create a DWord called IgnoreInstallPrerequisites and set the value to 1.
To enable the Next button if any of the install Readiness checks fail:
Add the key HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\InstallReadinessCheck\ to the registry. Create a DWord called EnableNextbutton and set the value to 1.
