Conflict when using GroupDocs.Viewer and some Aspose library in single project Leave feedback

Issue

When using the GroupDocs.Viewer together with one or more Aspose products (like Aspose.Pdf) in a single project on Windows 11, undefined unexpected conflicts may occurs, mostly in form of runtime exceptions of different types.

Cause

The problem occurrs because the project with GroupDocs.Viewer and Aspose product is running within a 32-bit IDE (this may include JetBrains Rider) on a 64-bit Windows 11 system. This mismatch between the IDE and the operating system caused conflicts in code execution and library loading.

Resolution

Reinstall the IDE by installing a corect version, which bitness matches the bitness of the operating system. In particular, 32-bit IDE for 32-bit operating system, and 64-bit IDE for 64-bit operating system.
