Something has gone wrong with my installation

My project is a Firemonkey project with Windows and OSX target platforms
When I open my form containing a chart I get the error "Class TChart not found"
I also cannot see TChart in the tool palette


I have tried the following steps to try to re-install TeeChart properly
1. Uninstall TeeChart
2. Reboot
3. Install TeeChart standard (the 85Mb version I am licensed for)
4. reboot
5. open Delphi Xe4
6. open the form containing the chart -> ERROR

Hi Uncork,

Please go to Component -> Install Packages and check that no old TeeChart packages are enabled and that those that you installed are enabled.

When I go to go to Component -> Install Packages, there is no TeeChart 2013

The only two Teechart packages listed (both unchecked) are..

TeeChart Standard 2012 Components
TeeChart Standard 2012 FMX Components

When I click to add "TeeChart Standard 2012 FMX Components" I get the following error ...

"Cannot Load FMXTee918. t contains unit
FMXTee.constants which is included in package FMXTee9180"

FMXTee9180 is one of the TeeChart packages that are shipped with XE4. This error message indicates that it's still being loaded by XE4. Can you please check again that no: Tee9180, DclTee9180, FMXTee9180 or DclFMXTee9180 are in the pacakges list?

None of the files you named are in the packages list

The only possible candidates I can see (both from FastReports) are shown highlit in the two screendumps attached (combined these screendumps show the full list of installed packages I have)

Thanks

Hi Uncork,

Yes, that must be the problem then, FastReports packages that are still using the old TeeChart versions. You could try disabling them and enabling new TeeChart packages. If that works then you should consider updating your FastReports for TeeChart components to your current TeeChart version. You could ask FastReports for packages compatible with your TeeChart version or, if you have FastReports sources, do something similar to what's explained in the QuickReport article.

Thanks

I already had the most recent FastReports FMX installed - but I do not use tCharts in it, so I ....

1. uninstalled FastReports FMX
2. Removed the remaining (presumably Embarcadero standard VCL) FastReports
3. Re-installed FastReports FMX - but EXCLUDED the Tee components

... and everything seems to be OK - or at least loads and I can enable the TChart components (labelled version 2012 but the description says 2013) then view my chart form again

Thanks for your help - you can close the ticket

Hi Brian,

You're welcome. I'm glad to hear that.
