Error reading: Property is read-only

[BasSchouten]

I just installed an upgraded Crystal Reports VCL into my Delphi 4 enivronment. The new version is 7.4.0.51

If i add a tCrpe component to an otherwise empty project and run it i'm getting the following error when it tries to create the Crpe:

Project Project1.exe raised exception class EReadError with message 'Error reading Crpe1.About: Property is read-only'.

Huh??? a readonly property that can't be read?????

Anyone got any suggestions?

Is it when you're trying to compile/build the project ?
If so - it might be the case that the source files are read only (or .dcu files or something) and when the files are being written to / overwritten (in the case of the dcu's) that Windows is recognizing that the files are set to ReadOnly.
Probably a long shot ...

Hi BasSchouten,

What are you trying to do with the about property?
You can't write anything to it. Maybe you have entered
a := where a = should be. This is a mistake easily made.

Heeft jullie bedrijf trouwens een website?

BobbaFet Everyone has a right to my opinion.

I'm not trying to do anything with the About property! I'v just added the control to an otherwise empty form, and try to run it.

It seems that adding the directory where the unit for this VCL are located to the Searchpath seems to make a difference. But i'm not sure it has solved the entire problem.
