You somehow messed up your installation. IIRC you are on Windows. Maybe it's easiest to delete (or rename) your Lazarus profile (default: c:\users\\AppData\Local\Lazarus, or, if you are having a secondary installation, it is the folder specified in (lazarus)\lazarus.cfg). This will erase all your user settings and remove your components. Then delete or rename also your Lazarus folder. Reinstall Lazarus. Afterward you must have a running system with working TAChart. Then reinstall the components missing, one by one to see if the issue is caused by one of your third-party packages. Before you open your project delete the folder with the compiled ppus of this project. BTW: the next time you post a screenshot copy it to an image processing program and save it as png. No doc, please (not everybody has MS-compatible software), and no rotated images. If you only want to report error messages, right-click into the message window and selecte "Copy" > "Copy selected messages to clipboard" or "Copy all messages to clipboard", and paste it into your browser message editor. ---------------------------------------------------------------------- frederic · 2016-07-03 15:49 you were  right. i followed your instructions and got two older projects working again thanks for that!!!

There is a help button at the top of the page, but it is too general. Specific question about this particular forum are not answered, e.g. which files types can be used as attachments, what is the max attachment size, how do I upload a Lazarus project, etc - at least as far as I can see with a quick glimpse. Maybe a moderator/admin is reading this...
