SysManager 1.99.5のダウンロード

[1.99.5] - 2026-09-12
When an update download fails, the tab now says why. Pressing Download and having it fail showed you
nothing at all: the progress bar disappeared, a "Manual download" button quietly appeared beside it, and
the sentence explaining what went wrong — a firewall blocking the connection, a server that was
temporarily unavailable, a timeout — was written to a line that had just been hidden. The explanation now
appears in amber under the update, and it wraps, so a long message is readable rather than cut off.
Fixed
- A failed update download shows the reason it failed instead of only a new button appearing.
- The message wraps to as many lines as it needs. The four explanations are full sentences that tell you
what to try next, and the old row would have shown about a third of one.
Verify the download
Get-FileHash .\SysManager-v1.99.5.exe -Algorithm SHA256
Expected SHA256: 04DDDBAC5BD5C910A9A9EA03A86F3B12EA5C40712C76C3ECC3768AA7A3D1D3A6
This build is not code-signed, so Windows will warn on first launch. That is
expected for a small independent app: see what the warning says and what to
click.
Code signing is planned through the SignPath Foundation,
which provides free certificates to open-source projects, with signing performed by
SignPath.io. Until then, the SHA256 above and the build
attestation below are what establish that a download is the genuine build.
Code signing policy
This release is not code-signed. The team roles, release-approval process and
privacy policy required by the SignPath Foundation programme
are documented in advance under Code signing
policy. That
documentation is a prerequisite for applying, not evidence of a certificate. The
attribution line naming SignPath as the signing provider will appear here once a
certificate is actually issued.
This program will not transfer any information to other networked systems unless
specifically requested by the user or the person installing or operating it. Full
privacy policy.
Verify where this binary came from
This exe was built by GitHub Actions from this public source, and the build is
recorded in the Sigstore public transparency log. With the
GitHub CLI:
gh attestation verify .\SysManager-v1.99.5.exe --repo laurentiu021/SystemManager
That proves which commit and workflow produced this exact binary, something the
SHA256 file cannot show, since it is published alongside the exe it describes.
Each release also ships SysManager-v1.99.5.sbom.json, a CycloneDX inventory of
every dependency resolved for this build.
