Title
Cannot Access Network Drive During Runtime

Summary

When installing an Install created by InstallShield, network drive cannot be found for installation destination.

Symptoms

When installing an Install created by InstallShield, network drive cannot be found for installation destination. This usually occurs if the user is administrator and the UAC is active.

Cause

The issue is due to a security measure implemented by Microsoft for everything after Windows 2000 SP2. An ID is generated for each device and for each logon session. Different logon sessions will not be able to see the device with the old ID. More details can be found on this blog.


Steps To Reproduce

  1. Create a sample BMSI installation
  2. Run install on a machine with UAC enabled
  3. Try to target a network drive

Resolution

  1. Disable UAC
  2. There are some cases where setting the EnableLinkedConnections registry resolves this issue.
