Opening/Saving/Exporting Projects crashes program.

[programnoir]

-- Pending support request. Yes, using 1.1.3

Accessing the file browsing dialogue in any context with a fresh installation of the new version of LMMS causes the program to hang up and crash. I have to make copies of existing projects, rename them, and associate their filetype with the program in order to open them. Exporting them has no workaround, so I cannot produce music, at the moment.

Steps to reproduce my issue:
0. Uninstall previous version of LMMS

1. Install LMMS
2. Launch LMMS
3. CTRL+O
   or in an existing project
4. Project > Save As
   or with a finished project
5. Project > Export Project

It's that simple, unfortunately. It feels weird... We wouldn't be seeing a "stable" release if it had this problem. Something must be wrong on my end but I was just using a fully-functional 1.1.0 so I can't imagine what is wrong. Windows 8.1.

Hey Circuitfry. It's neat to see your name around here.

The newest version of LMMS is actually 1.1.3 (not 1.1.0), which can be downloaded here. Perhaps writing "1.1.0" was a typo, but if not, you should definitely try upgrading to 1.1.3.

And for what it's worth, I installed LMMS 1.1.3 for 64 bit windows from that download link on a Windows 8.1 computer on which LMMS had never been installed before, and I could not reproduce the hang/crash for any of the 3 cases you listed.

@circuitfry,

Some strange things can happen during the install process that cause stability problems in Windows. The part you mentioned about file association is a clue that it is possibly a botched installation, which can happen from time to time.

Below are instructions to completely purge LMMS manually. If they don't work, a DLL may be shared on your system that is still in use or a conflicting DLL with the same name as one that ships with LMMS exists elsewhere.

If files are still in use, a reboot and manual purge will fix it, however if conflicting DLL file(s) exist elsewhere, we'll have to run LMMS.exe against Dependency Walker to help find the cause.

Purge LMMS on Windows

1. Uninstall from control panel

2. Delete (or move) C:\Program Files\LMMS if it exists (Right click CMD, run as Administrator)

   del  "%programfiles%\LMMS"
   del  "%programfiles(x86)%\LMMS"

3. Move config file .lmmsrc.xml

   move "%userprofile%\.lmmsrc.xml" "%userprofile%\.lmmsrc.bak"

4. Optionally, open regedit.exe, delete .mmp , .mmpz, LMMS Project, LMMS Project (compressed):

   HKEY_CLASSES_ROOT\.mmp
   HKEY_CLASSES_ROOT\.mmpz
   HKEY_CLASSES_ROOT\LMMS Project
   HKEY_CLASSES_ROOT\LMMS Project (compressed)

5. Optionally, open regedit.exe, delete LMMS Developers from:

   HKEY_LOCAL_MACHINE\SOFTWARE\LMMS Developers
   # and/or
   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LMMS Developers

6. Optionally, open regedit.exe, delete LMMS from:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\LMMS
   # and/or
   HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\LMMS

Thanks for the support, tresf. The manual purge unfortunately did not resolve it, so I'll go with you on the assumption of a conflicting DLL. I'm assuming Dependency Walker is a program that searches LMMS' dependencies with other programs' dependencies.

[programnoir]

After opening LMMS.exe in DependencyWalker, it is telling me that these files cannot be found:

• API-MS-WIN-CORE-KERNEL32-PRIVATE-L1-1-1.DLL
• API-MS-WIN-CORE-PRIVATEPROFILE-L1-1-1.DLL
• API-MS-WIN-SERVICE-PRIVATE-L1-1-1.DLL
• API-MS-WIN-CORE-SHUTDOWN-L1-1-1.DLL
• EXT-MS-WIN-NTUSER-UICONTEXT-EXT-L1-1-0.DLL

The last one likely isn't important if I'm not an NT User (Windows 8.1). The first one may not be 100% needed if I'm on a 64 bit kernel. The middle three, hm, hard to determine, but if it just can't access Windows stuff in general I suppose that would explain why I can't open/import/export/save any files with it. It's basically telling me that there are missing files. Shouldn't I be getting messages of conflicts?

Did you upgrade from a 32-bit OS?

You may need to reinstall the Visual C++ Redistributable Packages per http://answers.microsoft.com/en-us/windows/forum/windows8_1-performance/32-bit-application-fails-to-start-after-81-upgrade/b825723e-e2a2-4c8f-bd1f-10446a5d7059

I'm very interested in knowing the cause and solution to this.

This is a pretty new computer with 64-bit windows 8 to 8.1 so thankfully that's not the issue, we'll just have to and it just fixed itself that's just great I sure love it when computers act like magic and fix themselves that doesn't tick me off at all

I'm gonna go with "the purge worked and it was a delayed fix for whatever reason" for $200, Alex.

Resolved.

Ok closing with status of computers act like magic and fix themselves. :)
