INSTALLDIRwithFeatureMain.The following example silently installs all the features for INSTALLLEVEL=1:
msiexec /i <package>.msi INSTALLLEVEL=1 /quietThe following example, which is only available for IBM Semeru Runtime Certified Edition, will open the user interface in German:
msiexec /i <package>.msi ProductLanguage=1031
Reinstalling or upgrading
To reinstall the IBM® Semeru Runtimes in silent mode with default features, run the following command:
msiexec /i <package>.msi REINSTALL=ALL /quiet
If you want to upgrade the IBM Semeru Runtimes in silent mode, run the following command:
msiexec /i <package>.msi REINSTALL=ALL REINSTALLMODE=amus /quiet
As described in the installer user guide, the following options can be used with REINSTALLMODE:
- a: Force all files to be installed regardless of checksum or version
- m: Rewrite all required registry entries from the Registry Table that go to the
HKEY_LOCAL_MACHINE - o: Reinstall if the file is missing or is an older version
- u: Rewrite all required registry entries from the Registry Table that go to the
HKEY_CURRENT_USERorHKEY_USERS - s: Reinstall all shortcuts and recache all icons overwriting any existing shortcuts or icons
Setting REINSTALL=ALL is equivalent to REINSTALLMODE=omus
Note: Upgrading .msi files works only for the first 3 digits of the build number because of an MSI limitation. For example:
- Upgrading 8.0.2.1 to 8.0.3.1 works.
- Upgrading 8.0.2.1 to 8.0.2.2 does not work. Uninstall the previous
.msipackage and install the new one. - Upgrading 8.0.2.1 to 8.1.2.1 works.
- Upgrading 8.0.2.1 to 11.0.2.1 does not work. IBM does not provide upgrades for major versions. Either keep both installations or uninstall the older one.
Verification
You may optionally check that a Windows installer package has not been corrupted or altered. Follow the guidance on verifying Windows Installer packages.
You may also verify any executable (.exe) and dynamic link library (.dll) files installed by the .msi.

To list the available IBM Semeru Runtime Images use the IBM Cloud CLI command:
ibmcloud cr images --restrict appcafe/ibm-semeru-runtimes -
You can pull an image from the IBM Cloud Container Registry, without an IBM Cloud account. For example:
-
docker pull icr.io/appcafe/ibm-semeru-runtimes:open-11-jdk-ubi -
docker pull icr.io/appcafe/ibm-semeru-runtimes:open-11-jdk-ubi-minimal
-
Verify signature of the image
It is essential to verify the signature of the container image before running the image. As a prerequisite, you must have the following set up to verify the Linux container image.
- A Linux® environment
- gpg (install through Linux distribution's packages)
- skopeo (install through Linux distribution's packages)
Note:
For Linux container images, you can verify the signature of the container image while pulling the container image.
- Create a json file with the name “policy.json”. Copy the following text block and replace the keypath
with the location of the key ibm-java-public-gpgkey.gpg. { "default": [ { "type":"reject" } ], "transports": { "docker": { "icr.io/appcafe": [{ "type": "signedBy", "keyType": "GPGKeys", "keyPath": "<keypath of pub.asc key>"}] } }}An example is provided here for your reference. { "default": [ { "type":"reject" } ], "transports": { "docker": { "icr.io/appcafe": [{ "type": "signedBy", "keyType": "GPGKeys", "keyPath": "/tmp/ ibm-java-public-gpgkey.gpg "}] } }} - The IBM Java public key must exist on the Linux machine that will be used to verify the signed container image. To create the public key, copy the following text block exactly as shown into a text editor, and save it as ibm-java-public-gpgkey.gpg.
