Hello PV*Sol Forum.

I do not know why, but after the latest release i can't save my projects anymore. 

attached are print screens of the messages i got today and yesterday. 

I have lost the project files, hence they won't save, but i have exported the PDF files. 

 

Please provide me with a solution. I cant save any files at all!!!

Dear Nils Torbjørn,

Thank you for your inquiry.

This is a bug, and our development department is working on a solution.

For the time being, you can work around this by not using any special characters in the module area names. Please rename your module areas and replace all special characters, then you should be able to save the project file.

I have the same problem. Please let me know when it is removed!

Is there a way you could give me the option to go back to realease 2 and use that version until its fixed? 

 

Is it at this dialog box that you want me to not put ''Special Characters''? I have not changed this on any of my resent projects. 

 

Hi Nils,

yes, you can go back to R2 if you like:

We have already identified the cause of the error and will release a fix for that as soon as possible.

The renaming of the module areas should be done here:

Then go back from the 3D environment, and then you should be able to save again. As far as we know right now, all consonant letters with diacritics, e.g. ś or ć, need to be replaced.

Best regards,

Martin

Hi again moderator and thank you for helping me!

What pre-set character is creating this issue then? I do not change this parameter on a regular basis, it happens once, twice a year maybe. It is not me who puts special characters in that field it must be pre-set.  

And of course, I can’t access the version forwarded in the link, I got a colleague to test on his computer and he has the same issue.

 

Hi Nils,

sorry, I forgot the s in the link above, it must be https instead of http, of course.

The default name of the module area comes from the building name plus the roof surface name. Depending on the GUI language that you use, or also the file names of 3D models or so, this might already lead to those characters. 

If you use English as GUI language and the module area name does not contain any of those special letters with diacritics, and you are still not able to save the files, it would be very helpful for us if you could let us know (and send over the project file).

Best regards,

Martin

Hello there, I have the same problem, I am not able to save the project. It is possible to save until I insert a invertor into the project. After that i am getting a error in saving

 

Dear Lucia Svobodova, dear Nils Torbjørn, dear Josef52,

Thank you for your inquiry.

We have released the PV*SOL premium 2025 R4 version today. The bug should be fixed and you should be able to save your project file.

R4 still has the same issue 

Hi hom,

could you send us the project file that you are unable to save in R4, please? You can send it here by private message or to hotline@valentin-software.com (then with a hint to them, that they shall forward the project file to me).

Thanks,

Martin

How do I send the file when I am unable to save it ?

I thought it was a file that you already had from a previous version of PV*SOL premium. If it is a fresh file created in R4, then try disabling the option to save the characteristics in the options:

 

We are really sorry for the inconvenience caused by this. We had to replace a zipping library in our code, and apparently the new one behaves odd in various ways that we didn't see in our tests.

Best regards,

Martin
