32 bit assembly installation in GAC crashes

Hello,

I've a couple of assemblies which need to be installed in the Global Assembly Cache (GAC).

The assemblies are strongly signed, and using InstallShield, placed in the GAC folder of the target machine.

However, when I try and install the MSI, the installation crashes when it tries to install the 32 bit assembly.

The signing and placement procedures for both the 64 and 32 bit assemblies is the same, the assemblies are not delay signed either.

The OS is 64 bit.

What could be the issue?

Kindly advise.

Thanks.
