Notes about the GCR file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The GCR file type is primarily associated with 'GlowCode' by Electric Software, Inc.. This is a file you can visualize using the GlowCode reViewer tool which is part of the GlowCode 5.0 product.
