Converting hm3 to hm6 error

Unread post by Robert Nash »

I have H&M 6 and want to import an older H&M 3 project. So I converted the .hm3 to a .hmxz project. When I open the project, I get this error:

Code: Select all

Cannot load .....hmxz! Please ensure that you have sufficient rights to open the project.
ProjectOpen: This client is too old to work with the working copy at .....
You need to get a newer Subversion client. For more details, see
  http://subversion.apache.org/faq.html#working-copy-format-change
I have TortoiseSVN 1.9.5.

Any help would be appreciated.

Hi Robert,

First of all, I note that you have a SubVersion (SVN) message there. Since you are using a single-file .hmxz project, you cannot meaningfully use SVN. The .hmxz file is a compressed binary (actually a Zip) that SVN cannot do anything with. You need to use the uncompressed HMXP format, so that SVN can version all the individual project files.

Before doing anything else, please first make sure you are using the latest version of Help+Manual 6, which is 6.5.6 Build 3027. Check with Help > About and download the installer here to update if yours is older.

Then move the project files you are trying to convert out of your SVN system (you also cannot manage HM3 projects at all meaningfully with SVN, since they only use compressed binaries) and try the conversion again. If you continue to have problems, please send the HM3 projects to support AT ec-software.com (replace the AT with @) and we will check them for you.

Hello Tim,
I am not using TortoiseSVN with H&M at all. I'm a developer, and we have it installed on the computer for Delphi projects. The folder with the converted hmxz project is not under any SVN control. Also, all projects I do with H&M have the hmxz extension, and I have no probklem opening them. It's only the hm3 project and the converted version that are causing this error. I
Regards,
Henning

Hi Robert,

OK, those boxes are ticked. So please do send the .hm3 project you are trying to convert to support AT ec-software.com (replace the AT with @) and we'll check it for you.

I moved the project to another folder, and used the automatic (not the manual) conversion option when opening the hm3 file, and it seems to have solved the problem. Thanks, now I am on H&M 6 and enjoying your continuous development, making this the best editor on the market.

Thanks for confirming this. Note that as a HM6 user you also qualify for a big discount on an upgrade to the current version:
