You can install two versions of SigmaNEST on the same computer if you want to test a new version before using it in production. This process is called a "parallel upgrade," because you aren't uninstalling the current version of SigmaNEST before upgrading.
Parallel installations can also be useful if you need to install an older version of SigmaNEST for compatibility reasons.
Note: If you only need to have one version of SigmaNEST installed, you can speed up the upgrade process by using Live Update instead.
Checking for new releases
New releases are announced here on the Knowledge Base, and sometimes also through newsletters and blog posts.
If you're a community member with a current maintenance subscription, you can follow the Announcements topic to be emailed about new releases.
Whenever you open Live Update in SigmaNEST, you'll also see any available versions that you can upgrade to.
Note: Upgrades are included in the cost of the maintenance subscription. If your subscription has expired, you'll need to renew it before upgrading. Visit our website to learn more.
Download installer and find program info
- Visit the SigmaTEK Connect site to download the most recent version of SigmaNEST.
Click the download link for the most recent Complete Image.
Note: The complete image, while large, contains additional assets that SigmaNEST may require during installation
While the file is downloading, gather the following information for the currently installed version of SigmaNEST:
- Open SigmaNEST and go to Tools Help > System Report.
Under the Folders section, find the Program Files and SNData paths. These should look something like this:
System Path: C:\Program Files\SigmaTEK\SigmaNEST\
Data Path: C:\Users\Public\Documents\SNDATA\
Under the Database section, find the database name. It should look something like this:
Initial Catalog: SNDBase
- Close SigmaNEST.
- After the download has finished, double-click SNStartUp.exe.
Click SigmaNEST > SigmaNEST.
- Select your Language.
- Read the terms of the License Agreement, then accept it and click Next.
Select the Start Menu Group name for your install. Then click Next.
Note: Make sure this isn't the same name as your current SigmaNEST version. This name also determines which folder SigmaNEST will be installed in.
Choose whether to install SigmaNEST as a 32-bit or 64-bit program. If your operating system and post processor(s) are 64-bit compatible, select 64-bit, acknowledge the warning, and click OK. Otherwise, select 32-bit. Then click Next.
Note: All new and recently updated posts are 64-bit compatible. If you are not sure if you have a 64-bit post, please contact SigmaTEK Support for assistance before continuing.
Tip: The 64-bit version allows SigmaNEST to use as much RAM as you have available, so you should select it if you have a 64-bit operating system.
- Since you already have an existing instance of SigmaNEST, the SQL server is already installed. Clear the Install SQL Server check box but leave the Create Database check box selected. Click Next.
Select the SNData Folder check box, then choose where you want the SNData folder to be located (this should be a different path from your existing SNData folder). Click Next.
Note: Technically, you could allow both versions to access the same SNData folder. But we strongly recommend keeping them separate and just copying over any files you need.
- Click Next to begin the installation.
- When the database installer opens, use the instructions below to create or upgrade a database.
Click Finish to close the installer.
Note: When you open SigmaNEST for the first time, you will be prompted to connect to a database. Click Connect and select the database you created/upgraded.
Create a new database
- During installation, the database installer will open. When it does, review the information provided, then click Next.
Select your SQL Server and enter your login credentials.
Note: If no SQL servers appear, you may need to enter your security information first. If you are logged into the same Windows account (and computer) that originally created the SQL Server, you can Use Windows Security instead of entering a login and password.
Select the units you are planning to use, then click New Database. Enter a unique name and click OK. The database is added to the grid.
- Click Create/Upgrade Selected DBs.
- When the utility is finished, click Close. Then click Finish to exit the installer.
Copying posts and settings
After you have completed the installation, you'll want to copy the following information from the old installation to the new one:
- The post folder, which can be found in the SNData folder.
- Any other SNData files you want to transfer, such as parts, report templates, etc.
- Configuration settings, which are stored in the SNConfig.ini file. See Copying settings for a new user to learn more.
