Hello,

I downloaded PVSOL Premium 2020 from the website Solar Design Co and I bought the license, but doesn't complete the installation and giving me a/m error message in the title. Please see screenshot attached. What's the solution for this?

Hi Ragy,

this error is unknown to me, but it looks like a system issue to me. "msxml3.dll" is a system library located in C:\Windows\System32\. Can you see it in your system? Also be sure that no other process is accessing the PVSOL.ini file here:

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2020\PVSOL.ini"

or, if you install PV*SOL premium 2020 for the first time, check this file:

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2019\PVSOL.ini"

Hope that helps to identify the problem.

Kind regards,

Martin

Hi, Just got this error message on the new release 2022/R2. Please help

Runtime Error 146:4426

msxml3.dll:Accces is denied

Running installation file as admin

 

Hi Fredrik,

coudl you check if you have access to the following files:

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2021\PVSOL.ini"

and

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2022\PVSOL.ini"

as well as

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\Installation.ini"

Also check if these files are read-only or currently in use by another process or user.

Hope that helps, kind regards,

Martin

Hi, 

 

There were a read only on the 2022 PVSOL.ini.

Disabled it and installation went smooth

Thank you very much for the solution 

 

Here's the error message when I try to install/update to PVSOL premium 2024 R2

 

Runtime Error (at 59:4679):

Hi Afriyie

Could you ensure you do have necessary rights for the following files?

Kind regards
Frederik

Hi Frederik,

Turns out the "...PVSOL premium 2024\PVSOL.ini" file was read only. I disabled it and have now successfully installed the R3 update.

 

Thanks

Afriyie

@developer_fw im trying to update to PVSOL 2024 R8 here is the error message, 

 

even though read only for PVSOL.ini has been disabled.

Hey Afriyie,

have you also checked this file?

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\Installation.ini"

Also, you can check all older PVSOL.ini files in each subfolder of

"C:\Users\USERNAME\Documents\Valentin EnergieSoftware\"

 

Hope that helps,

kind regards, Martin

I just deleted the Documents "Valentin Sorftware" folder (on OneDrive).

Then the installation was finished properly.

 

Cheers M.
