Hi, I just returned home after 3 months of travelling and I wanted to import a business to Manager on my desktop PC that I had exported from my laptop. It told me the file format was incorrect. I assumed this was because the installation on my laptop was newer (I had installed Manager about 6 months ago on my PC and only about 2 or 3 months ago on my laptop). I am running Linux Mint 17.3 Rosa on my PC and I removed manager using sudo apt-get remove manager-accounting and it removed the package. I then downloaded the newest .deb package from the site and installed it using the gdebi Package Installer. Now when I run manager-accounting command, nothing happens. Program does not initiate, and doing a “ps -ef |grep manager” shows me that nothing related to Manager Accounting runs in the background either. Has anyone else reported a similar problem after updating? The software used to work, and I had installed it exactly the same way the last time, with the gdebi Package Installer. Any help would be appreciated, let me know if more information is required. Although I use Linux I am not a Linux expert so please let me know if I can help by giving more information. Thanks! ---

Search the forum for SQLite. There have been several discussions. And yes, opening an imported file that came from a newer version with an older version is the reason for your trouble. ---

Issue solved. Thank you for the SQLite tip, it set me on the right path. It turns out though, that I needed to install mono-complete package and run Manager through mono. I did the following things: 1. I followed the instructions in this thread for “Installing Prerequisite Software” : [Manager wont start ubuntu 14.04](https://forum.manager.io/t/manager-wont-start-ubuntu-14-04/7528) 2. I installed mono-complete package 3. I ran the application using mono with command: **sudo mono /opt/manager-accounting/ManagerDesktop.exe** I am now able to run the appcication, and I am indeed able to import the business as well which solves the original problem as well. Thanks for the help. ---

Three things 1. You will need to keep both machines on the same version to avoid potential data conflicts. 2. Generally there is no need to uninstall prior to downloading / updating 3. If you maintain your data files on a cloud storage folder (like Dropbox) and change your Application Path under About Manager to suit, then you remove the need to backup / restore when moving between machines. Read the discussion here > [@Relocating Data Filies](https://forum.manager.io/t/relocating-data-filies/4600): > > The object is to relocate the data files from appdata/local/manager to Dropbox for external backup. First, I created a Manager folder in Dropbox and then changed the path under About Manager. After changing the path and clicking Update the appdata-manager path still displayed but after a couple of Change/Update clicks the new dropbox-manager path displayed. [image] Second, I “moved” (not copied) the 4 files from appdata-manager to dropbox-manager and deleted the appdata-manager folder. On ope… ---
