Download Installer if this is the first time using Doggs V Studio. Extract to any location and click on Doggs V Studio.msi.
When installer shows the install folder change it to your sourcesdk\bin\ep1\bin folder and click OK.
If you have already installed Doggs Studio and are doing an update extract the files directly to your sourcesdk\bin\ep1\bin folder over writing any other files in it.
You can keep updated with help by checking online at http://haulinmods.com/dshelp or by downloading the latest from the files section and saving it to your ep1\bin folder.
You also can keep up with the latest nightly builds by downloading the latest exe file from files and save it to your ep1\bin folder.
As I configure Doggs Studio there will be newer builds. Check here often as there is not a set release schedule. Be sure to check your file system at ep1\bin as sometimes the uninstaller will remove other than application files. If you have a problem and get a Steam file system error refresh your sdk and it will replace the files removed. (InstallShield)
