What are the minimum requirements for the server running SpaceObServer on?

SpaceObServer is compatible with all Windows versions currently supported by Microsoft, including supported Windows Server versions (latest patches and updates should be installed). Please find more details

here. SpaceObServer can be used in a virtual environment.

The minimum requirements of SpaceObServer itself are so modest, that the minimum requirements of the oldest Windows version we support are even higher.

So, every operating system on which you can install SpaceObServer on (currently "Windows 8.1" / "Windows Server 2012" and higher) with at least approx. 160MB disk space for the installation fulfills the minimum system requirements.

What is the difference between the SpaceObServer license and the SpaceObServer Remote Client license?

You always need a SpaceObServer (Enterprise or Standard) license as base. This license includes the SpaceObServer user interface for reporting and the SpaceObServer scan service which executes the scans and archives the file system information into a database.

The SpaceObServer Remote Client only includes the SpaceObServer user interface only, without the scan service. You can install SpaceObServer Remote Client on additional machines in your network to generate reports for scanned directory trees, by accessing the data stored in the backend database. You can also use the SpaceObServer Remote Client for remote administration of scans.

Each instance/installation of SpaceObServer Remote Client need to be covered by one SpaceObServer Remote Client license.

Please find more detailed information how to use SpaceObServer in your environment here.

Which access rights / permissions are required to perform a scan on a drive or share?

Basically, the user account configured for scanning the scan target (configurable at "Scan > Configure Scans > Expert Settings") requires the permission to list the folders contents and to read the attributes.
On a share additionally read access on the share is necessary.

If you want SpaceObServer to also collect the NTFS permissions ("Scan > Configure Scans > Scan Options"), the permission to read the ACL is needed.

If you want SpaceObServer to also calculate MD5 hashes for the duplicate file search ("Scan > Configure Scans > Scan Options"), the read access for the file content is needed.

Every time I try to install or run the application, I get an error message "Could not validate software certificate." with an error code -2146762487.

How can I resolve this error?

This error code indicates that the root certificate is not trusted on the system. We just recently updated the certificate we used to sign our applications, so it still seems to be the case that this root certificate is not yet up to date.

These certificates are usually being updated and installed online and/or along with Windows updates. These updates might be disabled manually though.

Please check for pending or available Windows updates first.

If this doesn't work, please try to download and install the updated certificates manually. They are issued from GlobalSign and should therefore be considered safe:

Root certificate https://secure.globalsign.com/cacert/codesigningrootr45.crt

Intermediate certificate https://secure.globalsign.com/cacert/gsgccr45evcodesignca2020.crt

Please ensure to install the root certificate to the correct store (root certificates). Having Windows select the store automatically, it might select the wrong store for this certificate.

To install the root certificate, proceed as follows:

Download the certificate. If the browser reports that the file could damage the system, confirm this message with "Keep".
As the certificate comes from a trusted source (GlobalSign), this warning is not relevant in this case.
Right-click on file and select "Install certificate" in the context menu.
A Windows dialog opens. First select the storage location "Local computer" and "Next".
On the following page, select "Save all certificates in the following location" -> Browse -> "Trusted root certification authorities" for this certificate.
Click on continue/next until the import process is complete.

Proceed in the same way to install the intermediate certificate, but select the "Intermediate certification authorities" folder in step 4.

I try to scan my SharePoint sites using a certificate and the Sites.Selected permission, as told in the manual. How do i configure my site collections?

To grant permissions on the respective site collections to be scanned via TreeSize/SpaceObServer, the PowerShell cmdlet Grant-PnPAzureADAppSitePermission can be used.

Import-Module PnP.Powershell
Connect-PnPOnline -Url <SharePointSIteURL> -Interactive
Grant-PnPAzureADAppSitePermission -AppId <AzureAppID> -DisplayName <AzureAppName> -Site < SharePointSiteURL> -Permissions write

The user that is used for granting the permission must be a site collection admin of the respective site collection. The role 'Owner' is not sufficient.

For more information about the used cmdlets please see: https://pnp.github.io/powershell/cmdlets/

Where can I download older versions (e.g. versions that are still compatible with older operating systems)?

During your maintenance period, they are located at Downloads -> Older versions in the customer area, if you are logged in to your customer account.

You should be able to find the installation files and keys of the two last major versions there.

On 03/31/2022 a vulnerability in the Java Spring framework has been found and published, known as Spring4Shell. Is your application affected by this vulnerability and needs to be patched?

None of our applications depend on Java Spring or any other Java library and are thus not affected by this vulnerability.

All of our products are being developed in Delphi or C#. Although we use Spring4D(elphi) with some of the components, they are safe to use, because the reported vulnerability applies to Java Spring framework only.

This applies to all versions and editions of our applications (TreeSize, SpaceObServer, SpaceObServer WebAccess, HeavyLoad, SmartPOP2Exchange, Exchange Server Toolbox, SpamAssassin in a Box, SpamAssassin for Windows, SmartCallMonitor, SEPA-Transfer, ServerSentinel, and ShellBrowser). It is recommended to always use the latest available versions though to benefit from the latest patches, improvements, and features.
