FastReport Viewer Class C1 not found

in FastReport VCL 5

Hi there.

Newbie user here.

We have a software that generate reports using an embebded version of Fast Report.

We can create forms and new reports using this embebded version (FastReport 5.6) and can save/export as a prepared report (.FP3 file).

To allow other users to visualize these prepared reports, we installed FastReport Viewer Tool on all computers.

But every time we try to open a report, the viewer acuses the following error: "Class C1 not found".

What could it be?

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
