8. Edit `start-wekan.bat` with Notepad. There add [Windows computer IP address](https://support.microsoft.com/en-us/windows/find-your-ip-address-in-windows-f21a9bbc-c582-55cd-35e0-73431160a1b9) , like this, then Wekan will be at http://IP-ADDRESS-HERE/sign-in , for example http://192.168.0.100/sign-in but your different IP address. Add there wekan server computer IP address, not localhost. `node.exe main.js` is at bottom of `start-wekan.bat`, change there longer filename:
1. Updating only WeKan. Not updating Node.js and MongoDB.
1.1. Make backup, look at steps 2.1. and 2.2 below.
1.2. Download newest WeKan bundle .zip file from https://github.com/wekan/wekan/releases
1.3. Replace old bundle with new from that .zip file.
1.4. Start WeKan with `start-wekan.sh`
2. If it does not work, you maybe need to update Node.js and MongoDB.
2.1. Backup part 1/2. Try mongodump to backup database like this command. If mongodump command does not exist, download MongoDB Tools from https://www.mongodb.com/try/download/database-tools . Make backup:
```
mongodump
```
Backup will be is in directory `dump`. More info at https://github.com/wekan/wekan/wiki/Backup
2.2. Backup part 2/2. If there is files at `WRITABLE_PATH` directory mentioned at `start-wekan.bat` of https://github.com/wekan/wekan , also backup those. For example, if there is `WRITABLE_PATH=..`, it means previous directory. So when WeKan is started with `node main.js` in bundle directory, it may create in previous directory (where is bundle) directory `files`, where is subdirectories like `files\attachments`, `files\avatars` or similar.
2.3. Check required compatible version of Node.js from https://wekan.github.io `Install WeKan ® Server` section and Download that version node.exe for Windows 64bit from https://nodejs.org/dist/
2.4. Check required compatible version of MongoDB from https://wekan.github.io `Install WeKan ® Server` section and Download that version Windows MongoDB .msi installer from https://www.mongodb.com/try/download/community
2.5. Remove old Node.js and MongoDB (at Windows, Control Panel / Add Remove Programs).
2.6. Install newest Node.js and MongoDB.
2.7. Restore database with mongorestore, like this:
```
mongorestore --drop
```
If there are errors, try this instead:
```
mongorestore --drop --noIndexRestore
```
2.8. Start wekan with `start-wekan.bat`
2.9. If WeKan does not start with your old start-wekan.bat, download newest [start-wekan.bat](https://raw.githubusercontent.com/wekan/wekan/master/start-wekan.bat) and look are there differences to your old start-wekan.bat . For example, with this command, could work on WSL or PowerShell or Linux or after installing git:
```
diff old-start-wekan.bat start-wekan.bat
```
## b) How to fix errors on Linux bundle to create Windows bundle
