6 evidence-based answers
Is NS-RPC-windows-installer.exe safe?
Evidence-based answer
NS-RPC-windows-installer.exe appears safe. 2 of 74 antivirus engines flagged it; the 2 detections were treated as non-decisive after the wider evidence was weighed. Install it only when it came from the developer's official site or an official app store.
What is NS-RPC-windows-installer.exe?
Evidence-based answer
NS-RPC-windows-installer.exe is a software installer, about 5.2 MB. Our analysis did not identify a verdict-driving threat signal. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected NS-RPC-windows-installer.exe?
Evidence-based answer
2 of 74 antivirus engines flagged NS-RPC-windows-installer.exe, 2 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence.
What is the SHA-256 hash of NS-RPC-windows-installer.exe?
Evidence-based answer
The SHA-256 hash of NS-RPC-windows-installer.exe is ca22633bae88e927bba2e96c43920f4cafb93c77a000e4922d0f0365e277eac9, and its MD5 is 1b014f5ff25719146e1287a45af16ab8. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
Is it safe to install NS-RPC-windows-installer.exe?
Evidence-based answer
Based on the recorded evidence, NS-RPC-windows-installer.exe has a low observed risk. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of NS-RPC-windows-installer.exe?
Evidence-based answer
This report reflects the scan run on July 23, 2026. Because a file's hash never changes, the identity of NS-RPC-windows-installer.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
